Idaho’s color is concentrated along water at middle elevations rather than on the summits.

Aspen and cottonwood around Sun Valley, McCall and Swan Valley turn in the first ten days of October, the Sawtooths and Stanley within the same week, and the western larch in the northern forests around Lake Pend Oreille goes gold at the same time.

The Snake River plain and Boise finish in the third week of the month as the valley cottonwoods catch up.
