I added in last year to charts...there is a lot more snow in them thar hills than last year.

With that said, I have crossed Cottonwood Pass in mid-June in '05, '06 and '10 without a problem to stand on snow free Cirque Peak, if you are inclined to do some early Sierra hiking. However, Whitney is another thing. My guess is the only way the MMWT opens above the cables in June is if there is a warm spring.
