Hi, we are planning on summitting Langley in 2 weeks, going up Old Army Pass and down New Army Pass, as we read there is no snow on Old Army now.

Is there a place to filter water after the Cottonwood Lakes to Old Army Pass? Approximately how many miles is it from the last lake to the summit on Old Army Pass and how much time would it take at a slow, steady pace?

We researched online but we do not find any detailed guides as we could for Whitney.

If we started at 3am, how long would the entire take roughly take, from the parking lot to the summit and back?

I appreciate all your advice and info!

Janet
