Mapping the Catastrophic Traverse Mountain Landslide
When Traverse Mountain and the surrounding area were originally mapped, there were abundant omissions. These include but are not limited to: cataclasite in Dry Creek canyon mapped as glacial till; incomplete mapping on top of Traverse Mountain; and unidentified origin of rocks in many locations. The proposed hypothesis was that of relaxation off Lone Peak and/or extreme faulting on all sides. This wrong hypothesis influenced the incorrect mapping.
Important features we have mapped are: pebble dikes, molybdenite, pseudotachylite, cataclasite, and the Red Pine porphyry in the areas of Traverse Mountain, Dry Creek canyon, and Little Cottonwood canyon. Our discoveries have resulted in the theory that Traverse Mountain was a mega landslide. I am digitizing these features into an ArcMap document which will be a reference point for future study.
