Colorado Backcountry Skiing — Liability Disclaimers

This disclaimer supplements — and does not replace — PeakScout's Federal Land Liability Disclaimer. Both apply when using PeakScout for Colorado backcountry skiing planning.

CAIC Danger Scale — What Each Level Means for Backcountry Travel

• PeakScout displays CAIC data — PeakScout does NOT generate avalanche forecasts. PeakScout aggregates and presents CAIC zone-level danger ratings and supplementary snowpack information. PeakScout has no meteorologists, no avalanche forecasters, and no field observation program. The data you see on PeakScout originates entirely at avalanche.state.co.us. Always read the full CAIC forecast — including the detailed hazard discussion — before making any backcountry skiing decision.
• Forecast timing creates a hazard window. CAIC issues daily forecasts in the early morning. A forecast issued at 6 AM does not reflect new loading from afternoon snowfall, wind events, or temperature changes during the day. Conditions can deteriorate from forecast to field-time. PeakScout's CAIC data cache adds additional lag — the danger level you see on PeakScout may be hours old relative to the CAIC website.
• Rose diagram aspect/elevation data is zone-level, not slope-level. CAIC forecasts include danger by elevation band (below treeline, treeline, above treeline) and aspect (north, east, south, west, etc.). These sub-region ratings are still aggregated across the entire forecast zone. A specific slope may have hazard substantially different from the aspect/elevation rating for its zone.
• Special avalanche warnings require immediate attention. CAIC issues Special Avalanche Warnings for high-confidence elevated danger events outside normal forecast windows. PeakScout's polling interval means Special Warnings may not appear on PeakScout immediately. Subscribe to CAIC push notifications directly for real-time warning access.
• PeakScout is not responsible for decisions made using CAIC data displayed on PeakScout. By using PeakScout for backcountry skiing planning, you acknowledge that avalanche safety decisions are your sole responsibility and cannot be delegated to any data platform.

• SWE and snow depth are quantities, not avalanche proxies. A SNOTEL station reporting 20 inches of SWE tells you how much snow is present. It tells you nothing about whether a buried weak layer from two weeks ago is still reactive, whether recent wind has loaded a lee slope to critically dangerous depths, or whether a temperature crust is creating a sliding surface. These determinations require field observation and a trained eye.
• SNOTEL stations are placed in clearings, not representative avalanche start zones. SNOTEL instruments are installed in open areas with consistent solar exposure and minimal drift loading, specifically to measure precipitation-representative snowpack. This placement is the opposite of the terrain features — lee aspects, convexities, ridge-top cornices — where avalanche start zones develop. SNOTEL readings may significantly understate loading in avalanche-prone areas.
• Wind redistribution is not captured by SNOTEL. Wind is the primary factor in slab avalanche formation. A SNOTEL reading after a wind event may show the same depth as before, while wind-loaded slopes in the vicinity accumulated 2–4 times the station's measured snowfall as redistributed slab. SNOTEL does not substitute for visual wind-loading assessment in the field.
• Aspect, elevation, and slope angle are not captured. SNOTEL data is point-representative data at a specific station. The same storm may deposit 14 inches on a windward ridge at the SNOTEL site and 36 inches of dense wind slab on the lee aspect 400 feet higher. PeakScout cannot extrapolate SNOTEL data to specific slope conditions in your target zone.
• SNOTEL data serves as context for CAIC forecasters — not as a standalone safety signal. CAIC avalanche forecasters use SNOTEL data as one input among many, including field observations, pit data from observers across the state, and weather model analysis. Using raw SNOTEL data without this professional synthesis to make safety decisions understates risk systematically.

Terrain Traps

• Definition: Any terrain feature that increases the consequences of an avalanche regardless of its size. A small avalanche on an open slope is survivable; the same avalanche above a cliff band, in a gully, or into a forest is potentially fatal.
• PeakScout displays no terrain trap data. Topographic features that create terrain traps — convex rolls, natural half-pipes, cliff bands above open slopes, gully entrances, tree cluster boundaries — require direct visual field assessment. No satellite or topographic data product currently identifies terrain traps with the precision required for safety planning.
• Terrain trap avoidance is a core AIARE skill. AIARE Level 1 education specifically trains students to identify terrain traps as a primary route-selection factor. If you cannot reliably identify terrain traps in the field, you should not be making independent backcountry route decisions in avalanche terrain.

Cliff Bands & Consequential Terrain

• Cliff bands below ski lines are not shown on PeakScout. Colorado's backcountry terrain is highly variable. Many common ski descents have cliff bands, rock outcroppings, and technical terrain features that require route-specific knowledge to avoid. PeakScout terrain and satellite views do not have the resolution to identify cliff bands at the precision required for ski descent planning.
• Cornices are unstable overhanging snow features with no warning system. Wind-formed cornices develop on leeward ridge edges. Cornice collapse can trigger larger slab avalanches below and can occur without human trigger even on days of low regional danger. PeakScout does not map, forecast, or warn of cornice presence or stability at any specific location.

Tree Wells & Deep Snow Suffocation

• Tree wells are statistically significant killers in deep-snowpack forests. A tree well is a void of loose, unconsolidated snow around the base of a tree. Falling headfirst into a tree well — common in deep snow tree skiing — can result in Non-Avalanche-Related Snow Immersion Suffocation (NARSIS) within minutes. Unlike avalanche burial, tree well suffocation often happens in sight of partners and still results in death due to the difficulty of self-extraction.
• PeakScout does not identify tree well risk areas. Tree well risk correlates with forest density, tree species, and snowpack depth — not a data layer PeakScout provides. Deep-snow tree skiing carries inherent NARSIS risk at all times.
• The Never Ski Alone rule applies absolutely in deep-snow tree terrain. The only effective defense against NARSIS death is having a partner in visual contact who can extract you within minutes. Data platforms cannot substitute for a partner.

• Avalanche transceiver (beacon): A digital 3-antenna avalanche beacon is standard equipment for all backcountry travel. It must be worn on the body (not in the pack), switched to transmit before entering terrain, and all partners must know how to perform a companion search. Regular practice — not just annual refreshers — is required to maintain search speed.
• Shovel: Metal-blade shovels are required — plastic blades fail in consolidated debris. Strategic shoveling technique (V-conveyor method) is a practiced skill that significantly increases extraction speed. A shovel in the pack of someone who has never practiced extraction is substantially less useful than marketed.
• Probe: Probing skills determine whether a beacon pinpoint translates to a fast extraction or a long, damaging random-dig. Practiced probing is a skill, not a given.
• Airbag packs: Avalanche airbag packs deploy to increase surface area and reduce burial depth. Studies suggest airbags reduce mortality — under conditions where the user was able to deploy them. Trauma from impact, terrain traps, and deployment failure all reduce effectiveness. Airbag packs are not a substitute for avoidance and rescue skills.
• Satellite communicators: A SPOT, Garmin inReach, or equivalent satellite communicator is required safety equipment. Cell service is absent in most Colorado backcountry terrain. Even with a sat communicator, response times to backcountry avalanche accidents routinely exceed 2–4 hours. The communicator enables rescue; it does not guarantee survival.
• Helmets: Helmets reduce trauma risk during tree skiing and in terrain with cliffs. They do not provide avalanche burial protection. Their use in backcountry terrain is strongly recommended.

• AIARE Level 1 — American Institute for Avalanche Research and Education Level 1 course. The industry standard for recreational backcountry travelers. Covers snowpack observation, terrain assessment, decision-making frameworks, and companion rescue. Find providers at avtraining.org.
• American Avalanche Association (AAA) Rec1 — Equivalent to AIARE L1 under the American Avalanche Association curriculum. Also the accepted minimum standard for independent backcountry travel.
• Annual refreshers are necessary, not optional. Avalanche conditions vary year-to-year based on early-season storm patterns, wind events, and temperature cycles. An AIARE L1 course taken five years ago does not reflect current conditions. Annual practice days, current season CAIC educational content, and refresher training are essential maintenance for backcountry competency.
• Colorado Mountain Club, AIARE providers, and CAIC field days are all legitimate education resources. PeakScout provides no in-app avalanche education and does not recommend specific providers. The CAIC website (avalanche.state.co.us) publishes free educational resources and the current season's archived forecasts as learning material.
• Group decision dynamics kill experienced skiers. Heuristic traps — summit fever, expert halo, social proof — cause well-trained backcountry travelers to enter terrain they would otherwise avoid. AIARE training specifically addresses cognitive biases in avalanche decision-making. No data platform can address the social dynamics of your specific group on a specific day. That awareness belongs to you.

• 15-minute survival threshold for avalanche burial. Survival probability drops from approximately 90% at burial to approximately 50% at 15 minutes, then continues to fall rapidly due to asphyxiation and hypothermia. By the time a helicopter can be requested, dispatched, and flown to most Colorado backcountry terrain, the window for companion rescue has almost always closed. Your partners are your rescue team.
• Colorado SAR resources are volunteer-based. Colorado Search and Rescue teams operate with volunteer members who may not always be available for immediate response. Helicopter evacuations require favorable weather windows that do not always exist after avalanche events. Rescue is not guaranteed for any backcountry incident in Colorado — by law or by logistics.
• Calling 911 does not guarantee rapid response in backcountry terrain. 911 dispatch in Colorado routes backcountry calls through the county sheriff. Response coordination, aircraft availability, and terrain access limitations can mean hours between your distress signal and a field contact. Assume self-rescue will be required for any injury scenario that is not immediately life-threatening.
• Medical costs for backcountry rescue in Colorado can be substantial. Colorado does not automatically charge for search and rescue services for all incident types, but helicopter evacuation costs are routinely $10,000–$50,000+. Colorado Search and Rescue Fund registration (available through CPW for minimal cost) can reduce these costs — PeakScout is not affiliated with this program but strongly suggests registration before backcountry travel.
• Road closures can strand access to the injured party and prevent self-rescue exit. Many Colorado backcountry trailheads are accessed via roads that close seasonally or due to storm events. CDOT and USFS road closures that occur after you enter the backcountry can prevent self-evacuation and delay SAR access. Check road status before departure and plan for the road to close behind you.

Colorado mountain passes and backcountry access roads close regularly during winter months — often unexpectedly due to avalanche slide activity on the road itself, storm closures, and maintenance operations. PeakScout does not display real-time CDOT road closure data for access routes to backcountry skiing zones.

• Check CDOT COtrip (cotrip.org) the morning of your trip for all mountain passes and roads on your access route. A pass that was open yesterday may be closed this morning due to overnight slide activity.
• Major corridors at risk include: Independence Pass (CO 82, typically opens May–June, closes Oct–Nov), Cottonwood Pass (CO 306), Loveland Pass (US 6 — may close independently of I-70), Guanella Pass (FS 118), Molas Pass, Red Mountain Pass, and all forest roads on the access route to your trailhead.
• USFS forest road closures for avalanche hazard over the road are a separate category from highway closures. A forest road to a popular trailhead may be closed while the main highway is open. Check USFS Ranger District current conditions in addition to CDOT data.
• A closed road at exit can strand a backcountry party. Plan an alternate exit route when entering terrain whose only access road has a history of storm closures. PeakScout does not provide alternate route planning for road closure scenarios.

PeakScout is a data aggregation and briefing platform. It is not an avalanche safety consultant, guide service, route planner, or emergency alert system for Colorado backcountry skiing.

• Every backcountry skiing decision — including "go" or "no-go" for any day, zone, or route — is your decision alone. PeakScout data may inform your decision. It cannot make it for you and cannot take responsibility for its outcome.
• Data displayed on PeakScout may be cached, delayed, or incomplete. CAIC forecast data, SNOTEL readings, weather forecasts, and road condition information are all sourced from third parties and cached on update intervals ranging from 15 minutes to several hours. Conditions may have changed materially between PeakScout's last data pull and your use of the platform.
• Absence of a warning on PeakScout is not confirmation of safety. PeakScout does not display all known hazards for any backcountry skiing location. No data platform does. The absence of a warning for a specific area is not an "all clear" — it means that hazard is not in our data sources, not that the hazard doesn't exist.
• Using PeakScout as a planning tool creates no fiduciary, guide, or advisory relationship. PeakScout does not have a duty of care to individual users in the context of backcountry skiing planning. By using PeakScout, you acknowledge that you are responsible for independent verification of all safety-critical information through primary sources (CAIC directly, CDOT COtrip, USFS Ranger District) before making backcountry travel decisions.
