Results of Field and Laboratory Investigations Conducted for Remediation of Interim Response Actions, Other Contamination Sources. Volume 2. Appendixes
Abstract
This section contains details concerning the geology and hydrogeology of RMA in general and at the four hot spots investigated under this task order. Additional information concerning each site is contained in the study area reports. The RMA occupies approximately 27 square miles within the Colorado Piedmont section of the Great Plains physiographic province. The surficial deposits of this area are characterized primarily by a veneer of wind-blown and alluvial materials. Most of the topography at the Arsenal is greatly rolling; however, there are several prominent hills that contain outcrops of resistant bedrock. The Rocky Mountain Arsenal lies within the Denver Basin, one of the largest structural basins in the Rocky Mountain region. It covers approximately 60,000 square miles in portions of Colorado, Nebraska, Wyoming, and Kansas. The Denver Basin is an asymmetrical north-south trending syncline with its structural axis close to and parallel to the Front Range. Rock units on the west flank of the basin dip gently to the east through the dip becomes progressively steeper near the boundary between the Front Range uplift and the Denver Basin. The east flank of the basin generally dips to the west at one degree or less.
