Avalanche Slope Angle Map

Most avalanches occur on slope angles greater than 30 degrees. We have created slope angle maps for Utah and Washington. In these maps, slope angles between 25 and 30 are yellow, and angles above 30 are red. Clicking on the map will allow you to download a kmz file for use in Google Earth.
