Narration

Geology

The Scofield dam site is located near the northern plateau, a large area of nearly horizontal sedimentary rocks that has been elevated above the general level of the region. The rock column is made up of sandstone, shales, limestone and coal ranging in age from cretaceous to tertiary. Locally, the beds have been faulted into horst-graben type of structure. Pleasant valley in which the reservoir is located occupies one of the larger down-thrown or graben blocks. The dam site is located in a narrow canyon cut by Fish Creek as it drained eastward across on of the up-thrown blocks. The reservoir basin is partially structural and partly erosional being combined result of faulting and subsequent erosion. There is no evidence of recent movement on the fault. The basin is covered with a thick mantle of slope wash, which has formed an effective seal over the fault zones.
