A 60-year-old woman received third-degree burns walking in a thermal area in Yellowstone National Park in Wyoming this week, according to park officials.

The 60-year-old woman, who has not been named, was near the Old Faithful Geyser at the Wyoming national park this week when she stepped through a thin crust over scalding water, park officials said.
