Head west from Bishop on hwy 168 to the south lake trailhead. It's about an 8 to 10 miles to the top and the last 2,000ft is a scramble up.
Shooting from the saddle just below the summit might help you achieve a little more depth in the scene by adding snow and boulders. There is also a lot more room to manver around.
I was trying to summit Mt. Agassiz (13,891ft) by sunrise once but didn't make it up in time so I returned and this time I made it. Camped up there without a tent or sleeping bag, yes it was cold there always other ways of keeping yourself warm. That was supposed to keep me occupied for a little while up in the dark with no moon but it wasn't pitch black up there. There was plenty of reflected starlight so I could actually see in the dark pretty well. This is a shot from just below the summit looking at Thunderbolt peak and the palisade glacier which is California's largest glacier. Sad to say but it looks more like a large snowfield to me. More or less it was a memorable experience for me that I won't forget for quite some time.
