Diamond Creek Zone Context
Southeastern Idaho — Caribou Range
Diamond Creek covers the Caribou Range east of Soda Springs — high sagebrush parks, aspen pockets, and intermittent timber. Elk populations are moderate and tend to be visible from glassing knobs.
Soda Springs and Afton (Wyoming) are the realistic resupply points. Snow can close upper roads quickly.
