Rocky Flats represents a high-level pediment which is being slowly dissected by erosional processes. The deposit is fanned shaped with its apex near the mouth of Coal Creek Canyon and ranges in thickness from one to fifty feet as it overlies and transects bedrock of Pierre Shale, Fox Hills sandstone, and the Laramie Formation. Boulders up to two feet in diameter occur near the foothills, grading out to pebbles, cobbles, and sand lenses occurring along the eastern edge. Formed during pre- Wisconsin time, Rocky Flats is similar to smaller gravel-capped bedrock erosion surfaces that are common along the South Platte and Arkansas River drainages near the foothills. Rocky Flats Plant added to the National Register of Historic Places on May 19, 1997 (5JF.1227).
