Backcountry Intelligence
Be Awesome, Don’t Die
Navigate the backcountry with slope shading that adapts to the avalanche forecast, and tours you plan with your people.
Stay out of the red.
Red marks slopes steeper than today’s No Go angle, and the app says it plainly: “Traveling on Red Slopes is High Risk.” Routes are evaluated against the adaptive shading.
Moderate- Slope shading and route risk colors: High Risk
- Slope shading: Use Caution
- Route risk colors: Low Risk
Risk Conditions: Updated Live
We combine forecasts from U.S. avalanche centers with your own field observations to algorithmically map avalanche risk onto the terrain, slope by slope.
Avalanche forecast
Your zone’s avalanche center rates the danger. That rating sets the day’s slope angle limits.
Each slope is shaded by its angle against those limits. On clear slopes, check for Red Avalanche Start zones above, and stay out of their runout.
Your observations
What did you observe? Select warning signs you noticed, or None.
Saving will raise your personal display to Considerable. The official bulletin is unchanged.

Example. Not today’s forecast.
Adaptive slope shading
Shading follows the day’s avalanche danger rating. As the danger rises, more terrain is shaded.
Plan A and Plan B are example routes, not recommendations. Drag to move the map. Hold Ctrl or ⌘ and scroll to zoom, or use two fingers on touch.
One plan for the whole crew.
Tours keep the route, the checklists and your people together, from the forecast to the drive home.

The next morning Sam confirms Review the tour plan at 7:31 AM and Return time at car at 7:33 AM on his phone. In Alex's web app, Required steps updates to 2 of 2 participants have shared every step due so far.
On the mountain, Sam checks in with Taking a break at 11:20 AM. The check-in lands at the top of the tour's Updates in Alex's web app, and Sam's location shows on Plan A.

I have the avalanche training, experience and knowledge to assess the terrain I plan to travel through. I will document my reasoning. Lowering my personal display can increase my risk. Even experienced professionals make mistakes, and I may be killed in an avalanche. The official forecast remains unchanged.

Good questions. Clear answers.
A little more context before you head out.
What does AspectAvy help me understand?
AspectAvy brings terrain, avalanche forecast context and your tour plans into one place. Explore slope angle and aspect, review the forecast, and document the decisions you make with your group. It supports your preparation and judgment; it does not determine whether a slope is safe.
Can I use it on my phone and on the web?
Yes. Plan on the web and use AspectAvy on iOS. Your account connects your saved tours and other supported information across both. Check the app and your membership for the tools available to you.
What can I share with my group?
Tour planning brings your route, companions, preparation and sharing together. You choose who receives the plan and which information to share. Teammates and tour followers have distinct roles.
Does sharing a tour replace a rescue plan?
No. Sharing a tour keeps the people you choose informed. It is not a rescue dispatch service, and delivery depends on connectivity and your settings. Carry the right equipment, agree on a plan and know how to contact local emergency services.
Is the map on this page live avalanche advice?
No. This page contains an interactive terrain demonstration and an illustrative image comparison. They do not show current avalanche conditions and must not be used to choose or navigate a route. Open the app and consult the current local avalanche forecast before a trip.
Where can I see membership details?
Your account shows the current membership options, pricing and included tools. This keeps the offer you see here aligned with the options available to your account.
