2005-06 was a pretty heavy winter - let me borrow a some some photos from that year as a reference:

this is north of Muir Pass, just above Lake Mc Dermont on July 10, 2006 - about twice the snow we had last July... and when we met people heading south, our conditions were described as "freakin' Siberia" by some PCT hikers. 2006 was MUCH worse - just look a few pages back from the above link at Mather's south flank

where we didn't have any snow at all around July 20. 2010
and Forester's north side where my first two images were taken - except we didn't have all that white stuff between the far ridge where our snow was and the pass, where this photographer is standing looking north

and I've never seen the lake south of Glen frozen...
