Just don't do what I did and go in directly from the north. I found myself on increasingly steep slab that tested the adhesion limit of my shoes. It was not my happiest backcountry hour.
Took this shot while considering retreat/continue. The book of lies, er, guidebook says there's a route that way but if I were to try it again I'd head farther west and come in at an angle from the northwest.
A hiker from the Bay Area was caught at Iceland in a snowstorm a year later and died trying to descend to the north. I've always wondered whether he tried that route down, which would be literally impossible in foul weather without rope and belay.
Anyway, nice lake.
