Detailed Description

Large-scale cross-beds in the Paleogene Coalmont Formation southwest of Walden, Colorado, formed as a delta complex within a persistent lake. Sediments were chiefly eroded from the Proterozoic basement of the Park Range block to the west and transported a short distance to the Colorado Headwaters Basin.
