Huckleberry Ridge Tuff, Volcanic tuff formation in Yellowstone National Park, Wyoming.
The Huckleberry Ridge Tuff extends across Fremont County, displaying thick layers of rhyolitic pumice and ash from ancient volcanic events.
This geological formation emerged from a massive eruption that occurred 2.1 million years ago, releasing 2,450 cubic kilometers of volcanic material.
Scientists and researchers from around the world study these volcanic deposits to understand the evolution of North American geological processes.
Visitors can observe the volcanic formations through designated trails near Osprey Falls, along the Gardner River above Mammoth.
The tuff formation contains evidence of three separate eruption phases, each contributing distinct mineral compositions and structural patterns.
