In partnership with every U.S. based avalanche forecast center, daily forecasts are pulled into the App making it easy to read, drink your coffee, and plan your day’s tour.
Absolutely integral to avalanche safety—slope aspect is the cardinal direction the slope of a mountain faces. Understanding this allows you to gauge how much sun exposure that slope experiences, how much snow it could hold, and how prone it is to slide. Learn More.
This map Layer color-codes the angle of the slope on a given terrain feature with green representing lower angles and purple representing steeper. Mainly applied in a backcountry ski and splitboard setting, Slope Angle is the most vital measure of avalanche risk. Learn More.
The best data source for current snow accumulation data in the mountains is SNOTEL (Snow Telemetry) which uses remote stations to measure snow depth, snow/water equivalent, and temperature. Learn More.
