Summary:
Pg. 108-112. Cataract Creek Gravel is reworked Frazier Well Gravel. Crops out near Rose Well, Cataract Creek, and in isolated places north of Rose Well, eastern Hualpai Indian Reservation. Both gravel units consist of bedded but poorly sorted pebbles, cobbles, and small boulders as much as 20 inches in long diameter composed of red and white quartzite, vein quartz, granitic and gneissic rocks, chert, and sandstone. Age not stated. Frazier Well Gravel may have been deposited any time during Miocene or Pliocene but is probably no younger than early Pleistocene. Older than Robbers Roost Gravel.
