Less observations from this areaLess observations in this areaHigh Confidence areaHigh confidence area
The largest number of snowpack, weather, and avalanche observations come from the blue areas. They are the highest confidence areas for the advisory.
Fewer snowpack, weather, and avalanche observations come from the beige areas than the blue areas.
The avalanche advisory is based mostly on data and observations collected in the blue and beige zones. The advisory is inferred to the remaining pink areas where information is very limited.
The avalanche advisory for the Sonora Pass area is available through the Eastern Sierra Avalanche Center at www.esavalanche.org.
