Black Pool
Hot spring in Yellowstone park, United States
About
Black Pool is a hot spring in the West Thumb Geyser Basin of Yellowstone National Park in the United States.
The pool was cool enough up until 1991 for dark orange-brown cyanobacteria to grow throughout the pool. When combined with the blue of the water, the pool appeared to be an exceptionally dark green to almost black, hence the name.
