Belgian Pool

Belgian Pool is a hot spring in the Upper Geyser Basin of Yellowstone National Park, Wyoming. Originally named Oyster Spring, it was renamed after a visitor from Belgium fell into it in 1929 with fatal results. The spring is less hot than other features in the area, at about 180 °F, but still sufficiently hot for severe thermal burns. References to a "Belgian Geyser" in the 1930s may refer to this feature.
