Forest Fire Prevention Command & Dispatch System: In High Mountains and Dense Forest, a 1.4G Mesh Weaves a “Visible Prevention-and-Control Network”

Why Is a Forest Environment “Hard to Manage” by Nature?

Before choosing equipment or settling on a solution, the forest “battleground” itself must be understood. Every environmental trait directly dictates how communications, power and detection should be designed. Here are six realities that can never be avoided.

• Complex terrain, heavy occlusion: forest mountains, hills and ravines are dense, with large elevation differences; trees and bamboo blocks wireless line of sight and RF links, and ridgelines readily create signal blind zones. This interferes both with fixed-monitoring wireless transmission and with patrol personnel mobile communications — valleys, leeward slopes and dense forest are extremely prone to communication loss.
• Harsh, changeable weather: large day-night temperature swings, frequent heavy fog, rain/snow, lightning and gusty wind; hot and humid in summer, icing and frost in winter. Severe weather not only causes equipment faults, link fluctuation and declining solar output, it also worsens public-network attenuation, so on-site reporting of fires and hazards by patrols is easily blocked.
• Scant infrastructure, fragmented public coverage: the vast majority of sites have no mains power, so monitoring relies on solar energy storage; forest lacks communications infrastructure, and 4G/5G covers only edge areas. Patrol personnel have no fixed supply, terminals run on their own batteries, and offline-ops communications assurance is extremely difficult.
• Poor access and maintenance conditions: monitoring sites are scattered, deep-mountain vehicles cannot reach many, and repair cycles are long; patrol routes are scattered and wide, dense-forest blind areas are hard to hike, traditional manual checks easily miss routes, and work traces are hard to supervise.
• Human-dominated, highly concealed ignition sources: more than 90% of forest fires are human-caused — ritual burning, slash-and-burn, open-air cooking, leftover cigarette ends. Early-stage fires are mostly understory smoldering or surface embers with no smoke and no flame, which cameras and thermal imaging cannot identify; only close-range manual inspection can. This is precisely why “human prevention” is always the last line of defense in a fire-prevention system.
• Clean electromagnetic environment with random mobile interference: standing interference in forest is low; nearby villages, base stations and mine areas produce 4G/5G, WiFi and intercom clutter. Patrol personnel keep moving and terrain constantly changes, so signal fluctuates markedly and fixed communications parameters cannot fit the mobile single-soldier scenario.

Citation capsule: forest-area fire prevention is hard because of six realities: terrain occlusion, harsh weather, fragmented public coverage, poor access and maintenance, ignition sources more than 90% human and highly concealed, and a random electromagnetic environment. The first four dictate how fixed monitoring is done, the last two how human-prevention communications are done — and concealed human ignition sources are precisely the variable that hardware-minded thinking most easily ignores yet that most decides success, which is why “human-prevention communications backup” must be part of the solution.

Why Do Both Prevention and Suppression Stall on “No Network”?

Forest fire prevention’s demand on communications is by no means “just having a signal” — it is pinned by three hard constraints.

Pain point 1: vast terrain, spare population, public coverage cannot reach deep mountains

A county-level forest often spans dozens to hundreds of kilometers, with watchtowers, ranger points and entrance checkpoints scattered across ridgelines and hollows. Carriers build base stations by ROI and will not blanket an unpopulated forest. The result: ranger points are “manned posts with no network” year-round, fire reports rely on manual phone calls or cannot be raised at all, and video surveillance is useless because there is no backhaul channel.

Pain point 2: rolling terrain, line-of-sight communications cannot cross that ridge

Even with wireless equipment, most civilian point-to-point bridges are line-of-sight (LOS); a single ridgeline or slice of dense forest breaks the link. Between points at a mountain forest farm there is, precisely, one ridge after another. This is not a power problem; it is “cannot cross” caused by choosing the wrong frequency band. Later we explain specifically why 1.4 GHz can cross.

Pain point 3: once a fire starts it hits “triple outage,” and on-site command is completely out of touch

The most lethal part of an incident is “broken road, broken network, cut power.” Fiber burns, base stations lose power, roads close, and the frontal suppression force loses contact with the headquarters. With thick smoke, flying embers and changing wind direction in the fireground, without real-time location and backhaul the commander can only “guess by experience,” and crew safety cannot be confirmed in real time. That “wartime link break” is precisely what the peacetime-deployed network can rescue.

Stringing the three pain points together, the conclusion is clear: the forest needs an autonomous network that “does not depend on the public network, crosses mountains and obstacles, supervises monitoring in peacetime, and guarantees command in wartime” — this is exactly the value starting point of ad-hoc networking, but it is also scenario-dependent and cannot blindly pile 1.4G Mesh across the board.

Citation capsule: forest fire prevention communications are pinned by three hard constraints: vast sparely-populated terrain keeps public coverage from reaching deep mountains, rolling terrain keeps line-of-sight bridges from crossing ridgelines, and once a fire starts it hits “broken road, broken network, cut power.” Stacked together, the conclusion is to bound the boundary first rather than blindly pile 1.4G Mesh: deep-mountain valley roads and the fireground no-network zone belong to the ad-hoc network, while watchtower/ranger-station interiors that already have WiFi coverage use a roaming relay client only.

From “Seeing” to “Managing,” What Is So Hard?

The environment determines that it is hard to do; the difficulty then spans six major blocks. The environment traits above explain “why it is hard”; here we break down “where the difficulty and the blocker lie.” Many projects do not fail for lack of equipment but because these short boards stack on top of one another.

1) Difficulty of fixed-monitoring wireless transmission

• Fiber construction is costly and forest coordination is difficult, unfit for wide-area deployment;
• Public coverage is insufficient, and data traffic fees accrue continuously over the long term;
• Ordinary wireless bridges rely on line of sight, and trees grow taller year after year to occlude the link, causing frequent monitoring disconnects.

2) Difficulty of off-grid power supply

• Solar generation is affected by sunlight, canopy occlusion and season, with blackout risk during consecutive overcast/rainy days;
• Storage batteries lose capacity in low temperatures; lacking remote monitoring, aging faults cannot be pre-warned;
• Patrol single-soldier terminals have no external replenishment, and long-duration field operations put heavy pressure on endurance.

3) Difficulty of video perception and detection

• Visible-light cameras fail at night; thermal imaging is limited by rain/fog and vegetation occlusion, and long-distance detection is restricted;
• Leaf motion, glints and flying birds cause massive false alarms;
• Shallow understory smoldering fire is concealed by the canopy, so equipment has an inherent missed-detection blind zone.

4) Dedicated difficulty of manual-patrol communications

• Heavy dependence on the public network: deep mountains have no mobile signal, so hazards and fires cannot be reported in real time;
• Short intercom range: weak mountain penetration prevents cross-valley coordination;
• Lack of offline communications: personnel entering a no-signal area go out of touch, a safety risk;
• Lack of digital supervision: traces and hazard records cannot be retained, and missed patrols or unreported items are hard to manage.

5) Difficulty of human-machine coordination and linkage

• Technical-prevention monitoring and manual patrol are independent; when monitoring raises a suspected alarm, the nearest ranger cannot be dispatched on site to verify;
• When a patrolman finds a concealed ignition source, the PTZ camera cannot be quickly moved in to collect evidence;
• Alarm information and patrol ledgers belong to two separate systems, and emergency dispatch efficiency is low.

6) Difficulty of construction and maintenance

• Mountain pole installations demand high standards of wind-resistance, lightning protection and waterproofing; scattered sites and late fault discovery;
• Patrols lack a standardized communications work flow, and hazard reporting and fire handling lack a regulated mechanism.

Citation capsule: six short boards of a forest fire prevention system: fixed-monitoring wireless transmission, off-grid power supply, video perception and detection, manual-patrol communications, human-machine linkage, and construction/maintenance. The first three are old hard problems of traditional monitoring; the last three are short boards of the human-prevention system long neglected — and manual-patrol communications is the most lethal of them: ignition sources are 90% human, yet patrols are exactly the segment with the least communications support, directly deciding prevention success.

Which Section of the Forest Uses 1.4G Mesh, and Which Uses the Roaming Client?

Many integrators want “Mesh across the whole forest” right away, which is not economical. The sound approach is to cut the forest into two classes by “distance + whether basic network exists.”

In summary: the forest’s “wilderness segment” and “fireground no-network segment” belong to 1.4G Mesh; any “campus segment / near-adjacent segment” where WiFi coverage exists and mobile equipment only needs to roam between hot zones belongs to the YN300 roaming relay client. Walking on both legs with the right tool for each segment gives the best cost and effect.

Citation capsule: the forest network boundary is cut into two classes by “distance + whether basic network exists”: tens-of-kilometers deep-mountain backhaul and the fireground no-network zone must use 1.4G Mesh ad-hoc networking (P1/P2/P3, cross-mountain multi-hop, non-line-of-sight); watchtower/ranger-station interiors, camps, and mobile inspections that already have WiFi can use the YN300 roaming relay client (cheaper, more power-efficient). The test is one sentence: wilderness with no network belongs to the ad-hoc network; campus and near-adjacent segments belong to the roaming client.

Real Events: the Muli “Triple Outage” and the Yajiang Fire

The 2023 Muli Plateau “Triple Outage” Verification, Sichuan

In October 2023, a combat verification was run on the Muli Plateau, Sichuan: the site was at an altitude of about 3,630 m, and the incident site was about 20 km from the command center with mountain occlusion in between. The solution used a UAV carrying Mesh ad-hoc networking to build an air-ground integrated emergency communications network, backhauling on-scene audio/video and location data in high definition, completing beyond-line-of-sight UAV emergency communications assurance. The organizers were the Department of Science, Technology and Informatization of the Ministry of Emergency Management and the China Fire and Rescue Institute. Note the difficulty: 20 km is not visible in a straight line — a mountain lies in between, and an ordinary line-of-sight bridge cannot break through at all; only a combination of low-frequency diffraction plus an aerial relay works.

The 2024 Yajiang Forest Fire, Sichuan

In March 2024, in the Yajiang forest fire in Sichuan, the Wing Loong-2H and the Tengdun Double-Scorpion carried electro-optical reconnaissance pods, satellite communications, and all-network aerial base stations, continuously cruising and relaying above the fireground to hold stable coverage of about 50 km² over a long period. Sichuan added 279 county-level 370M ad-hoc base stations and 380 trunking base stations, forming a hybrid architecture of “aerial base station + ground ad-hoc network.” The division of labor behind this is exactly what we described earlier: the aerial base station handles large-area last-resort coverage, while the ground ad-hoc network goes into mountains and forest to extend command to the very front of the fire line.

Citation capsule: the Muli Plateau 3,630 m “triple outage” verification and the Yajiang fire verified the same playbook: UAV-carried Mesh + ground ad-hoc network + aerial base station build air-ground integrated emergency communications. At Muli, the site and command center were about 20 km apart with mountain occlusion, and an ordinary line-of-sight bridge cannot break through, so low-frequency diffraction plus an aerial relay is required; at Yajiang, multi-aircraft platforms such as the Wing Loong carried aerial base stations for areal last-resort coverage while the ground ad-hoc network penetrated mountain valleys and forest to extend command.

Why Do Civilian High Frequencies Fail in the Forest?

To understand why the forest must use low frequency, look at what actually happens when an electromagnetic wave passes through vegetation.

The relationship between attenuation and frequency

Vegetation leaves and branches are rich in water, and water molecules strongly absorb microwaves. The higher the frequency, the shorter the wavelength, and the worse the scattering and absorption on encountering leaves. The vegetation attenuation model in [ITU-R P.833] shows that at 2.4 GHz and 5.8 GHz, the equivalent attenuation of a single-story deciduous stand is far greater than at 1.4 GHz. That is the physical cause of “no signal once in the woods” — not bad equipment, but the wrong band.

• Diffraction: the diffraction-propagation model of [ITU-R P.526] shows low frequency bends around edge obstacles more easily; the 1.4 GHz wavelength is far longer than 5.8 GHz (about 21 cm vs about 5.2 cm), so it more easily bends around ridgelines and trunk undulations to sustain the link.
• Penetration: low frequency attenuates less through vegetation and terrain undulation, has stronger non-line-of-sight capability, and holds more steadily through dense forest and over the canopy.
• Coverage: at the same transmission power, the 1.4 GHz effective coverage distance in forest far exceeds 5.8 GHz, meaning fewer relay points and less investment.
• Legally high power: as a 1.4G private band, it may legally use higher transmission power to make up long-distance attenuation — something the civilian ISM band cannot do. [FCC 47 CFR Part 15] sets power and duty-cycle limits on license-exempt high-band devices, further capping the usable link budget of civilian high frequency in long-distance forest backhaul.

The civilian WiFi band was designed for indoor local-area use — forest is its “forbidden zone”; the 1.4G private band turns “crossing the woods and riding over ridgelines” from impossible into an engineering routine.

Fig. 1 | A relay-link illustration of the forest-area 1.4G Mesh radio wave passing through the canopy and bending around a ridgeline (actual deployment scenario).

Citation capsule: the physical root cause of civilian high-frequency failure in the forest is vegetation absorbing water: the [ITU-R P.833] vegetation attenuation model shows equivalent attenuation rises markedly as frequency increases, so 2.4G/5.8G single-story deciduous stands attenuate far more than 1.4 GHz; add “one low, one high” — the 1.4 GHz wavelength of about 21 cm diffracts and penetrates more easily, [ITU-R P.526] supports it bending around ridgelines, and the 1.4G private band can legally use high power. That is why 1.4G Mesh is the natural forest choice.

How Is the Forest-Area Network Built?

Architecturally, we split the forest network into three layers: dispatch, backbone, and access. With the responsibility of each layer clear, product selection has a basis.

The P3 platform is sited at a county/city-level/front-line command post; monitoring watchtowers and patrol points use P1 to carry front-end video and sensor data back over multiple hops. When a fire breaks out, the same set of nodes is adjusted in place: P1 is redeployed to commanding heights upwind of the fire, P2 lifts off to fill coverage gaps, and P3 converts in place into a fireground command platform, smoothly switching a “prevention network” into a “suppression command network.” For points near camps and watchtower buildings that have power and network, use YN300 to bring station interiors, duty rooms and parked patrol vehicles into one unified network without occupying a 1.4 GHz channel.

Fig. 2 | Two-tier networking: 1.4G Mesh covers the forest wilderness segment, and the camp/watchtower near-adjacent segment joins via a YN300 roaming client.

Citation capsule: the forest network has three layers: the dispatch layer uses the P3 portable command platform as the on-site command post and monitoring center, doubling as 4G/5G backhaul; the backbone layer uses the P1 backpack radio deployed along ridgeline watchtowers for long-term backhaul of monitoring and patrol data; the access layer uses the P2 airborne node to lift off and fill gaps, and the YN300 roaming client to take the camp/watchtower near-adjacent segment. When a fire occurs, the same set of nodes converts in place into a suppression command network — P3 becomes the forward command post, P1 is redeployed to fireground commanding heights, and P2 lifts off for cross-mountain relay.
— Forest Fire Prevention Command & Dispatch System

How Do the Prevention ↔ Suppression Two Networks Switch Over?

The key is “switch,” not “rebuild”: the long-online batch of nodes in the prevention network need not be dismantled during a fire — redefine routing priority and bandwidth allocation, push command traffic to the very front, and the fire-line crews’ handheld terminals simply join the network. [IEEE 802.11s] defines the self-organizing and multi-hop routing protocol of wireless mesh networks; the same nodes reuse the same network to add or remove service flows — that is the value of the same protocol, same band, and free mixed grouping.

Citation capsule: the same set of 1.4G nodes can become two networks: in peacetime the prevention network is permanently installed along watchtower/checkpoint/ridgeline positions, mostly chain + mesh, backhauling monitoring, thermal imaging and fire alarms; during a fire the suppression network has P3 set up a forward command post, P1 redeployed to commanding heights upwind of the fire, and P2 lifting off for cross-mountain relay, with multi-hop command audio/video reaching the fire line directly. The switch relies on [IEEE 802.11s] ad-hoc routing redefinition rather than rebuilding, so the nodes deployed in peacetime are not dismantled during a fire.

How Is Power Supply Reliability Assured for Long-Cycle Deployment?

The prevention network is “unattended, on line year-round,” which determines that it follows a different logic from temporary network rigging. The reliability design revolves around three things:

• Long-term power supply: fixed nodes carry solar panels + storage batteries; battery sizing and installation details are covered in deployment step 3, “Power system configuration optimization,” sized for a “3–7 consecutive overcast/rainy days without dropping” margin to keep unattended sites on line year-round; watchtowers with mains power directly use external power.
• Redundant links: key monitoring points are equipped with standby relays; a single-point power outage or cable break routes around automatically, so one node fault does not take down the whole string.
• Scheduled inspection: periodically use a drone or manual checks to verify link quality and bandwidth and assess whether points need to be added or the topology adjusted, preventing silent degradation.
• All-in-one backhaul: the front end integrates thermal fire detection, and anomalies alarm to the platform automatically, upgrading “watching monitoring” into “automatic discovery” and reducing manning effort.

For points near camps that have mains power and network, use the YN300 roaming relay for station/duty-room/patrol-vehicle access — low power and flexible, able to hold year-round on-line operation without occupying a 1.4G backbone channel.

Citation capsule: long-term forest deployment fears most “the power goes out and no one manages it”; reliability revolves around three things: long-term power supply — fixed nodes carry solar + storage batteries, sized for 3–7 consecutive overcast days without dropping, and watchtowers with mains power use external power directly; redundant links — key monitoring points carry standby relays with automatic reroute on a single-point fault; scheduled inspection — periodic drone or manual verification of link bandwidth. Storage uses low-temperature-type batteries with remote monitoring to prevent silent degradation.

Core Problem: Four Hurdles, “Why It Can’t Be Prevented”

Pulling the environmental traits and the six major difficulties together, forest fire prevention is intrinsically stuck on four hurdles. The first three are the ceiling of the technical-prevention system; the last is the life-and-death point that truly decides success or failure yet is most often ignored.

1) Technical prevention has inherent coverage short boards

Wireless monitoring always faces four contradictions — link stability, power continuity, detection accuracy, and full-area coverage: fiber is costly, wireless bridges are constrained by vegetation, solar power is limited by climate, AI algorithms have false positives/negatives, and the concealed human ignition source under the forest canopy cannot be detected at all. Relying on monitoring alone can never achieve full-area fire prevention.

2) Human prevention lacks reliable communications backup (the critical pain point)

Human ignition sources are the leading cause of fires, and concealed smoldering fires can only be found by manual inspection. But existing patrols depend on public networks and legacy intercoms: communications break in no-network areas, multiple squads cannot coordinate, work processes cannot be supervised, and hazard reporting lacks a stable channel. The lack of communications support for human-prevention forces is the single greatest vulnerability of the forest fire prevention system.

3) The system is disjointed between machine and human, unable to close the loop in handling

Monitoring only generates alarms, and patrols only do on-foot inspection; the two lack a two-way linkage mechanism. It cannot achieve “equipment alarms send people to verify; personnel-find hazards get re-checked by video.” The strengths of technical and human prevention cannot complement each other, and the handling chain breaks.

4) Heavier on hardware construction, lighter on long-term operations assurance

Many projects only complete the installation of monitoring equipment, without optimizing communications and power solutions for forest terrain, lack human-prevention communications support, and have an incomplete maintenance mechanism. The system is usable short-term but its fault rate keeps rising mid/long term, making it unable to support routine fire prevention work.

Citation capsule: forest fire prevention is stuck on four hurdles: technical prevention has inherent coverage short boards (fiber is costly, wireless is blocked by vegetation, solar is limited by climate, understory smoldering cannot be detected); human prevention lacks reliable communications backup — human ignition sources are the leading cause and concealed smoldering fires can only be found manually, yet patrols are the segment with the least communications; the system is disjointed between machine and human and cannot close the handling loop; and hardware construction is emphasized over long-term operations. The first two are solved by network selection, the third by platform linkage, and the fourth by an operable, replicable project.

From Survey to Human-Machine Linkage, How Are the Eight Procedures Done?

1. Early survey and overall point-site planning

• Fixed monitoring should prioritise mountain tops and lookout-tower commanding heights, reserving room for tree growth; use terrain-simulation tools to verify the Fresnel zone of wireless links and avoid occlusion.
• In parallel, plan Mesh communications gap-filling nodes to cover valleys, dense forest, main patrol arterials and monitoring blind zones, balancing video backhaul and patrol single-soldier communications needs.
• Plan nodes in layers: backbone nodes (long-distance backhaul along ridgeline watchtowers), collection nodes (front-end monitoring/sensors), and mobile gap-filling nodes (vehicle/airborne/single-soldier).

2. Wireless communications networking deployment (fixed equipment + mobile single-soldier integrated)

• Adopt a hybrid architecture of “commanding-height directional bridges + in-forest Mesh ad-hoc network + single-soldier mobile communications”: 5.8G directional bridges build backbone high-speed links carrying video; 2.4G Mesh nodes are used to fill dense-forest gaps and improve diffraction performance.
• Equip patrol personnel with Mesh single-soldier terminals that support trunking intercom, location, and image/text/video reporting even without the public network.
• Plan channels uniformly to avoid co-channel interference; deploy 4G/5G links at important lookout points as communications backup.
• Strictly comply with radio-management regulations; high-power point-to-point equipment must be registered with the local radio authority as required.

3. Power-system configuration optimization

• Tilt and raise the solar modules to face south, avoiding canopy occlusion; size storage for 3–7 consecutive sunless days and use low-temperature-type batteries.
• Insulate and dehumidify the battery compartment, remotely monitor voltage/current, and pre-warn on low voltage.
• Equip portable charging gear for single soldiers to secure patrol terminal endurance, building a dual power-assurance scheme of “fixed points + mobile terminals.”

4. Equipment selection and full-area lightning protection

• Use dual-spectrum, wide-temperature PTZ cameras for monitoring, with lens heating and defogging.
• Implement three-level lightning protection across the system: pole lightning rods, surge protectors at both ends of network/power/RF cables, and grounding resistance ≤ 4 Ω.
• Use industrial waterproof, drop-resistant single-soldier terminals; enclosures use rust-proof aluminum alloy with dehumidification/temperature-control modules to prevent internal condensation from corroding PCBs.

5. Civil construction standards

• Design pole foundations for mountainous gust wind loading to ensure wind resistance; use waterproof connectors on cables and reserve thermal-expansion/contraction slack.
• Raise enclosures above the ground to avoid water and snow accumulation, and add anti-theft devices.
• Design small Mesh gap-filling nodes lightweight, fit for rapid installation in roadless areas.

6. Dedicated deployment of manual patrol “fire-and-electrical inspection” communications

• Build an offline trunking intercom dispatch system on the forest Mesh backbone to enable communications for patrol squads across valleys and zones.
• Equip offline smart patrol terminals that can cache hazard images/text/video in no-signal areas and automatically sync once communications recover; establish standardized reporting flows for outdoor-fire use, ritual hazards and understory smoldering fire.
• Enable a personnel-location system with real-time position viewing, track playback and check-in patrols to eliminate skipped and missed patrols.

7. Build a closed-loop human-machine linkage mechanism

• When monitoring raises a suspected-fire alarm, the platform automatically pushes it to the nearest patrolperson for on-site verification and feeds back the result.
• When a ranger reports an ignition hazard, the platform moves the nearest PTZ camera to zoom in and collect evidence.
• Manage alarms in grades — general hazard, suspected fire, confirmed fire — linked with emergency broadcast and message push, forming the complete “monitor — report — verify — handle” closed loop.

8. Platform integration and maintenance assurance

• Reserve platform interfaces to support integration with forestry and emergency higher-level command platforms, aggregating video, fire alarms and patrol-ledger data.
• Adopt a “remote monitoring + periodic on-site inspection” model: remotely view equipment power, signal and personnel patrol status; run site-wide inspection before the critical fire-prevention season.
• Stock spare parts such as bridges, surge protectors and single-soldier terminals at management stations to shorten repair time.

Citation capsule: forest fire prevention deployment follows eight procedures: survey and point-siting, wireless networking, power optimization, lightning protection, civil construction, patrol communications, human-machine linkage, and platform maintenance. The last three are most likely to be cut — human-prevention communications, human-machine linkage and maintenance assurance — yet exactly these decide whether the system can hold long-term. In practice, prioritise placing nodes at human-accessible commanding heights and pulling mains/solar power, which is more efficient and reliable than “hand-carrying everything / swapping batteries.”

Solution Product Recommendations: What Configures Best with This Package

Here are the product recommendations that best fit the current solution, in order of priority.

Citation capsule: the most balanced forest fire prevention product combination is “P3 portable command platform + P1 backpack radio + P2 UAV-carried node” — the brain, backbone and gap-filling trio covers the greatest demand of the forest no-network segment; when the budget is tight, secure the P1 backbone and P3 first and make coverage solid. When the camp/watchtower near-adjacent has WiFi roaming needs, add YN300 as a low-power finish, but never as a cross-mountain backbone.
