You can customize the color scheme by clicking on a segment of the legend.
Highlight a specific slope angle range. This is useful for finding slopes in your target angle, i.e. 20-30º for low angle days. Or for highlighting flat areas to avoid.

On mobile, this layer is produced from the USGS 1/3 arc-second DEM (10m resolution).
On desktop, this layer uses the Mapbox Terrain DEM which has higher resolution in some places.
Slope angle is not a perfect indicator of avalanche potential. It's always possible that the angle has been underestimated, or that the actual angle is steeper on small, localized slopes. Always verify angles with a slope meter, and seek proper education before venturing into avalanche terrain.
