Congress Pool


Congress Pool, which emerged in 1891-the same year scientists from around the world converged upon Yellowstone for the Fifth International Geological Congress. A visit most times of the year will show a Congress Pool that appears pale blue in color. Due to the variable nature of Norris features it is possible to see the same pool looking muddy and boiling violently.
