I live a couple of hours from Yosemite in CA.
So I'm about 2 hours between the Sierras and the Coast.

It's in the 90-100's this last few days so the warm weather started really melting off the snow above 7000-8000ft, it's about in the 70-80's at that altitude.

Snow plows have not made it over Tioga pass yet though, maybe by Memorial day, last weekend in May. They still have 16 ft of snow there.

To give you a scale, the little cascade water fall is about 300-400ft tall.
Bridalveil is 620ft, Tueeulala Falls is 800ft and Wapama is actually 1300 ft, 1700ft if they had not dammed it up, you cannot see the upper cascade easily though.

Regards,
Tom Barr
