"Old" Yellowstone in southern Idaho: amazing deposits of pyroclastic flows from explosive eruptions

Journey to Salmon Falls Creek reservoir in southern Idaho with geology professor Shawn Willsey to investigate the spectacular evidence of huge, hot pyroclastic flows that barreled across the landscape when the Yellowstone hot spot occupied this region about 8-10 million years ago. Impressively, the sheer volume and heat of these ash clouds caused the ash to weld together and deform, forming a ductile mass with tight folds. The resulting deposit is called a rheomorphic ignimbrite, compose of several rock types that reveal insights into the eruption. Support these videos!
