The Artists' Paintpots area in Yellowstone National Park is temporarily closed due to safety concerns.

Eyewitness news has learned that yesterday afternoon a hiker from Utah suffered serious burns after falling through an established trail into a pool of near boiling water.

Before yesterday park authorities were unaware of the pool's existence.

Jeanette Hogan received burns to her ankle and lower leg. She was taken to EIRMC, treated, and released last night.
