Exploring Yellowstone National Park

YELLOWSTONE NATIONAL PARK, WY - SEPTEMBER 18: One of the many hot springs in close proximity to the iconic Grand Prismatic Spring in Yellowstone National Park's Midway Geyser Basin is viewed on September 18, 2022, in Yellowstone National Park, Wyoming. Sitting atop an active volcanic caldera, Yellowstone, America's first National Park, is home to more geological hydrothermal features (geysers, mud pots, hot springs, fumaroles) than are found in the rest of the world combined.
