Yeah, it was tough to pick out in the dark. Coming down I was able to note key features in the light of day (on the other side).
As far as the slab, yes you make a beeline for where the MR passes to the south of the Iceberg buttress above UBSL. The way there is Class 2-3, or you can go over a sand hump and end up right at the lake.
My bud is going to be just fine. He stepped on a bad piece of talus and fell ribs first on a boulder. After giving the worst scream I've ever heard, he tested it and thought he would be good to continue.
We pushed a little further to UBSL to have him test how bad it was, (UBSL has cell service and spots where a chopper can land) and once the adrenaline of the fall wore off he realized any strenuous movement on his right side produced a sharp pain where he fell.
We were afraid it might be a broken rib (which can puncture a lung). Going up was out of the question and we debated going down on foot. With the crossings and the E- ledges I decided to call the Sherriff's dept (Not 911, not using my PLB) to see if a busted rib posited a severe danger. They patched us through to Inyo SAR. Upon hearing what happened Cpl. Vaughn thought it would be best to send a chopper to make sure that Dave didn't fall again and make the injury worse.
We waited about 3 hours, Dave got triaged (no clean break) and helivacked to Lone Pine Hospital.
Turns out to be a bad bruise that was causing his big back muscles to spasm painfully. They gave him Vicodin and discharged him upon finishing his X-ray.
I got to hike out.
