Donner Summit Snow Lab

The Snow Lab’s average date for 0 snow depth is May 23rd.  This year, it’s going to happen today.  Right now, there are only 6 inches of snow at the study site and that snow is going to melt completely away within the day.
“The most surprising event was that we had 0 snow depth here on January 19th and that had never happened in the history of the snow lab.  That period was historically dry here.  We got our first permanent snow on January 20th.” – Randall Osterhuber
“Last year [2010/11] we had permanent snow starting November 17th.” – Randall Osterhuber
