We would summit Mount Oso this day from Rock Lake. 8 hours camp-to-camp.

Rock Lake

We saw Moon Lake again as we gained the ridge between Moon and Rock Lakes.

On the way to the talus slope. Our route is right above Alan, with the red backpack.

This photo gives a fair indication of the steepness of the loose talus slope. The slope above the talus to gain the ridge was a bit steeper in spots.
