Excelsior Geyser Crater is about 100 yards north of Grand Prismatic Spring. These two features are the main attractions in Midway Geyser Basin. Excelsior last erupted in the 1880s, throwing water perhaps as high as 300 feet and discharging enough water to raise the level of the nearby Firehole River by up to a foot. This geyser when active, was the largest ever recorded in Yellowstone. Excelsior Geyser C13882145 - Grand Prismatic Spring is one of the largest and most beautiful examples of a common hydrothermal feature in Yellowstone National Park and one of the largest hot springs in the United States. The prismatic, colorful features come from several sources; the deep blue in the center is the clear super-heated water circulating up from the subterranean heat source and shows a pair of convection currents, like a pair of eyes. As the water cools at the edges of the pool and on the sinter terraces, bacteria and algae produce the rainbow of colors.
