Snowpack Observations

Details

The Mount Shasta Avalanche Center (MSAC) conducted a snow survey at the Gray Rock Lakes survey course today. Snow surveys have been conducted by the California Cooperative Snow Survey (CCSS) since 1929 when the California legistlature recognized the importance of tracking the water content of the snowpack for water users of the state. This was based on the work started by Dr. James E. Church in the early 1900's on Mount Rose. Today over 50 federal, state, local, and private entities are part of collecting this data and MSAC is privileged to be a part of it.

The table below shows the present and recent trends of the survey at Gray Rocks.
