An Oregon man died in Yellowstone National Park on Tuesday, after leaving a boardwalk and falling into a scalding hot spring.

Park officials identified the man as Colin Nathaniel Scott, a 23-year-old Portland resident, in a press release Wednesday.

According to park rangers, Scott walked about 225 yards off the boardwalk near Pork Chop Geyser at the Norris Geyser Basin, before slipping and falling into a hot spring. Officials tried to recover the man's body, but canceled the effort after they couldn't locate his remains.

"We extend our sympathy to the Scott family," park superintendent Dan Wenk said in the news release. "This tragic event must remind all of us to follow the regulations and stay on boardwalks when visiting Yellowstone's geyser basins."

The springs in Yellowstone can reach a blistering 160 degrees Fahrenheit, more than enough to cause third degree burns in a few seconds. On Saturday, a father and son were treated for severe burns in the Upper Geyser Basin after they walked off the boardwalk as well.

Signs posted around the park warn visitors not to walk out onto the sensitive and dangerous ground around the geysers, but tourists regularly disregard the rules.

The Norris Geyser Basin will remain open, but park officials are urging visitors to remain on the marked pathway.
