One of the many unique geological features at the bottom of
Yellowstone Lake. It’s formation layers are clearly visible. Credit: Global Foundation for Ocean Exploration
Hollow pipes, some several feet in height, were found rising up from
the lake bottom. It is thought that these are the old plumbing systems
of now dormant geysers. Credit: Global Foundation for Ocean Exploration
Creatures can feed off of the hot, mineral-
rich fluid seeping from these features. A colony of hydroids can be
seen here. Credit: Global Foundation for Ocean Exploration
