Marys Lake Dike Dam

Overview
There is relatively little in the project records concerning the damsite geology.  The geologic summary, Colorado-Big Thompson Project, states that the reservoir is situated in a local divide area of granite rock.  Another reference states that the rock under the dam was jointed granite.
