Winter Continues Up In Mount Charleston

Well, another cold and windy day in Las Vegas. Up in the Spring Mountains and Mount Charleston, they got up to 5 inches of snow.
I've been wondering when all the snow will be melted off of Mount Charleston. Normally, it is gone by June 1st, but I bet we will still see snow on the 4th of July, in it's highest peaks that are pretty well shaded.
Global Warming? I don't think so.
