The two mountain ranges reach altitudes of 12,000 feet but they are very different geologically. The Beartooths, above, were formed by a huge granite batholith pushed up through the Earth's crust, while the Absarokas, below, are more volcanic. The Beartooth Plateau is lake country with great fishing, but the Absarokas offer better habitat for wildlife, like the Grizzly Bears featured in our previous newsletter. The volcanic rock of the scree fields are the source of moth larvae that feeds hundreds of the grizzly bears during the late summer.
