I just returned from Horseshoe Meadow. Yesterday the air quality was bad in Lone Pine although not so bad late afternoon near 10k' elevation at Horseshoe Meadow. This morning I couldn't even tell if there were ashes in the sky up there, and conditions got better in Lone Pine. You could see the summit.
A USFS rep told me that they were expecting (not 100% sure) conditions to significantly improve by Wednesday.
