Traverse Mountains before the landslide. Several million years later, the landslide occurred, carrying the upper half of the granite-bearing pebble dikes with it. The

New research suggests that the entirety of the East
Traverse Mountains, from the Point of the Mountain to Corner Canyon, is a single mega-landslide, 57 km in area, that was emplaced in a landslide event between 6.5 to 6.1 million years ago. The East Traverse Mountains previously included the upper
