TR to follow, but I did end up at Cottomwood Lakes from Wednesday until yesterday (8/26 - 29). It was smoky in the evenings (coming in around 7) until probably midnight or so, but the days were quite clear. Up OAP on the backside of Langley looking down the valley was pretty clear as well. Driving into Lone Pine on Wednesday I was nervous about all the smoke I saw, but up that high it wasn't much of an issue those days. The wind did seem to be shifting as we exited yesterday and I imagine it was quite smoky yesterday evening.
