Thanks for the report, Wandering Jim. The altitude takes its toll on everybody at those elevations. I'm hoping to get over to that area in a couple of weeks myself, and I'll certainly be taking Diamox before I even get there.
How much water did you carry up to your Army Pass area camp? It had to be a long dry stretch to the top of Langley and back down.
When you do Williamson, you will most likely do it via Shepherd Pass. There is an easy trail from there directly down to the JMT, so you can then climb Whitney and exit via the Main Trail (if you get an exit permit), or exit over Cottonwood Pass or Army pass, ....or the Mountaineers Route on Whitney.
