Successfully summited Mt Muir, which is just to the south of Whitney on Saturday Nov 5 via the Whitney Trail. Had great weather. Their was quite a bit of snow above Guitar lake. The cables had packed snow not ice. Micro spikes were very helpful, and there was a solid boot pack. Many people turned back on the switchbacks just above the cables. The angle here is steep and you would want to be comfortable in snow travel to continue confidently.
Most of the ice on the trail was below trail camp, very slippery without micro spikes.
