Yellowstone National Park rangers spent Monday responding to numerous incidents, including several involving significant injuries to visitors:

A 37-year-old man from Provo, Utah, suffered thermal burns on the Solitary Geyser Trail in the Upper Geyser Basin. He was transported by ambulance to West Yellowstone, Montana, and from there by airplane to the Salt Lake City Burn Center.
A 65-year-old British national from Bangkok, Thailand, suffered injuries when he was thrown into the air by a bull bison at Mammoth Hot Springs. He was transported to Memorial Hospital in Livingston, Montana.
Yellowstone employees respond to an average of 700 emergency medical calls each year.
