BILLINGS, Mont. (AP) — A 23-year-old Portland, Oregon, man who died after falling into a Yellowstone National Park hot spring this summer was looking for a place to "hot pot," or soak in the park's natural thermal features.

Colin Scott's sister, Sable Scott told investigators she and her brother left the boardwalk near Pork Chop Geyser on June 7, according to a report by Deputy Chief Ranger Lorant Veress.

As she took video with her cellphone, her brother reached down to check the water temperature and fell into the scalding pool.

KULR-TV obtained the National Park Service's final report through a Freedom of Information Act request.

Search and rescue rangers spotted Colin Scott's body in the pool the day of the accident, but a lightning storm prevented recovery efforts.

By the next day, workers could not find any remains.
