By Yellowstone Volcano Observatory April 15, 2024 Monument Geyser Basin: A Unique Vapor-Dominated Thermal Area in Yellowstone National Park Just south of Norris Geyser Basin is a little-visited thermal area called Monument Geyser Basin. The “monuments” there are unique in Yellowstone’s above-water hydrothermal areas and resemble the “black smoker” deposits found at the bottom of the ocean.
