Just labeling some of last year’s photos, and I came across this from August 22, 2016:
This is by far the earliest we’ve ever had a visible dusting of next winter’s snow on the mountains.
FWIW: I’m not sure of the exact date, but in 2004 the same spot still had last winter’s snow at least a week into August.
P.S. That whole mountainside in the background was ravaged by a late forest first a couple months after this snowfall.
