High on Mount Everts, way above above Mammoth Hot Springs in Yellowstone National Park, lies an amazing outcrop that exposes the 2.1 million year old Huckleberry Ridge Tuff (the largest of Yellowstone's recent three eruptions) where it overlaps older Cretaceous sedimentary rocks. Join geology professor Shawn Willsey as he catches his breath and shows the exceptional geologic features created as the ash from this eruption baked the underlying soil and rock, turning it red. Learn how the initial ash fall preceded the bigger and more deadly pyroclastic flow and also created an exceptional unconformity.
