Rocky Mountain foothills near Denver, CO.

Foothills or piedmont are geographically defined as gradual increases in elevation at the base of a mountain range, higher hill range or an upland area. They are a transition zone between plains and low relief hills and the adjacent topographically higher mountains, hills, and uplands. [1] Frequently foothills consist of alluvial fans, coalesced alluvial fans and dissected plateaus.
