Medicine Lake is a fascinating geological place.
Most of the water you see in this photograph will disappear
and will almost entirely disappear by early November.
Millions of gallons of water are not evaporating, they are simply disappearing.

The local natives named this place "Bad Medicine Lake" because they did not understand the strange phenomenon that occurs here every spring and fall.
It has recently been discovered that underground streams and
rivers that run off from this lake may travel hundreds of miles
in several directions. No one knows how far they go.
