Foot (and shoe) found floating in a Yellowstone park hot spring

Park officials are investigating the discovery, spotted in Abyss Pool in the southern part of the national park

An investigation is under way after a Yellowstone employee spotted part of a foot, in a shoe, floating in a hot spring in the national park.

The discovery was made on Tuesday at Abyss Pool, in the southern part of Yellowstone, and led to the temporary closure of the West Thumb Geyser Basin and its parking lot. The area has since reopened.
