Images From Yellowstone: America’s First National Park
Mario Tama / Getty An aerial view of visitors walking around Grand Prismatic Spring in the Midway Geyser Basin on May 24, 2026, in Yellowstone National Park, Wyoming. Grand Prismatic Spring is the largest hot spring in the United States at more than 300 feet wide at its widest point, and more than 120 feet deep. The colors outside the pool’s blue center are created by “thermophiles”: heat-loving microscopic organisms that flourish in many of Yellowstone’s hot springs. Mario Tama / Getty A bison
