Narration

Geology

Wanship Dam and Rockport Lake are located on the Weber River where it cuts through shale, siltstone and sandstone beds of the Frontier Formation of Late Creracious age. Bedrock is primarily shale and siltstone with sandstone beds that form resistant ridges. Impure coal and bentonite are interbedded with the shale. The dam and reservoir are on the north limb of the Uinta Mountain uplift. The beds dip 25 degrees to 35 degrees downstream. Several northeast trending thrust faults cross the Weber Valley in the vicinity of the dam and reservoir.
