An Oregon man fell into a hot spring at Norris Geyser Basin in Yellowstone National Park on Tuesday, according to a news release.

Colin Nathaniel Scott, 23, from Portland, Ore., was with his sister, Sable Scott, when the incident happened about 225 yards off the boardwalk near Pork Chop Geyser in the northwest part of the park.

Sable Scott reported the incident to rangers Tuesday afternoon.

Rangers used extreme caution because of the thermal area's hazards and confirmed Scott’s death Tuesday evening.

Wednesday, rangers will focus their efforts on recovering the body.

The Norris Geyser Basin is open. However, visitors should anticipate temporary closures in the area until the investigation is complete.

“We extend our sympathy to the Scott family,” Park Superintendent Dan Wenk said. “This tragic event must remind all of us to follow the regulations and stay on boardwalks when visiting Yellowstone’s geyser basins.”

This fatality is the second known thermal-related incident to occur in the park during the 2016 summer season.

On Saturday, a father and son suffered burns in the Upper Geyser Basin after walking off the designated trail in the thermal area.
