English: Depicted are four major calderas of the Yellowstone volcano, numbered in order of eruption: Island Park, Henry's Fork, Yellowstone, and West Thumb. Each caldera is also labeled with its associated tuff deposit and dates for each eruption/deposit from recent scientific literature. This is an improvement on the previous version of this diagram located here. The previous version was itself an adaptation of a diagram appearing in the 2021 National Park Service publication "Yellowstone Resources and Issues Handbook", itself adapted from the original diagram created in 2000 by Smith & Siegel for their book, "Windows Into the Earth: The Geologic Story of Yellowstone and Grand Teton National Parks". This diagram is a simplified version of a diagram made for Wikipedia.
