I summited Mount Langley, going up via Old Army Pass (and down New) in September of 2016. The most current information from the NPS on the Pass this year is this:
"7/26 - Snow free but has suffered extensive damage from rockslide on steep slopes with high risk consequences. Experience with route finding and cross-country travel is required."
Since you summited in late July, you've seen what the park service is describing here. I take it it's not really an issue, but I'm curious to know if any of the sketchiness described looked like any kind of a problem... I'm planning a August 21 hike up Mt. Langley prior to my August 23rd ascent at Mt. Whitney.
