Just home from 8 days in the high country of Idaho, with a few dips into Montana and Wyoming. The trip started with several large smoke plumes rising from the mountains, seemingly in every direction we looked, but mid way through we had a couple inches of snow, and ended the trip with blue, instead of smoky, skies. 28 F in the camper outside of Island Park was the coldest temp we measured, but I think it was a bit colder in the Lemhi Mountains, (low 20's?) we kept the heater on low, so it was 40's in the camper overnight. Feeling the change for sure.
