BEAVER DAM MOUNTAINS GEOLOGY
The class will traverse the Beaver Dam Mountains, a tilted block of the earth’s crust at the western edge of the Colorado Plateau, in a zone of tortured rock variously called “the transition zone” between the Colorado Plateau structural province and the Basin and Range structural province. The route will follow the Apex Mine road over Bulldog Pass, a graded dirt road with a few rough spots and mudholes if it has rained. In passing westward through the range we traverse rocks ranging in age from 2 million to 1.7 billion years in age, and encounter evidence of multiple episodes of mountain building. Erosion of canyons in the range has exposed folds, faults and giant landslides. Stops will include short hikes and fossil hunts in rocks of various ages. Limited to 12 participants.
