Yellowstone Rock

Formerly known as Idaho Travertine, Yellowstone Rock is based in Idaho Falls, ID. Under the new ownership of the Little Shell Tribe of Chippewa Indians, the company is in the process of expanding production and quarrying capacities. At this time, 2 quarries are in operation, producing 4 color variations of travertine. Additional quarries with more colors and standardized products will soon be offered.

Yellowstone Rock travertine quarries are located throughout the greater Yellowstone National Park geographic area in Idaho and Montana. This beautiful stone, created by the Yellowstone supervolcano, was deposited in limited areas through hot spring sediments created by geothermal activity. This stone is truly one of a kind. We are confident you will agree.
