Dragons Mouth Spring

Description

Dragon's Mouth Spring has captured imaginations for centuries. The Crow saw the steam as snorts of an angry bull bison. An unknown European American gave it the current name. Its previous names have included Gothic Grotto, Blowing Cavern, and The Belcher. The surging action has decreased since 1994; no one is sure why. In 1999, more dramatic changes occurred: The water temperature dropped ten degrees and the color changed from green to chalky white.
