Slope highlight

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.

Data source

This layer is produced using the highest resolution data available, including LiDAR at 1m resolution covering most of the US.

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.
