Scott’s sister, Sable, reported the incident to park rangers who searched for the man’s body into Wednesday. The temperature of the spring is known to reach levels that can cause third-degree burns after just seconds of exposure.

"We extend our sympathy to the Scott family,” 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.”

Elsewhere in the park, another tourist group wandered from the Grand Prismatic Spring trail onto the spring itself, KTVQ-TV reported. This comes less than a month after a Canadian group was caught walking in the same area .

"I could not believe that we were witnessing something, because we have been paying attention to all the things that have been happening on the news recently. I was shocked, and I was upset. I was really upset," tourist Judy Held told KTVQ. The group was reported, and a park ranger escorted them out.

These incidents follow on the heels of several others. On June 6, a father and son suffered burns in the Upper Geyser Basin after walking off the designated trail, according to the release.

Last month, two tourists loaded a Yellowstone bison calf into their vehicle , fearing it would get cold and die. The calf had to be euthanized after it was unable to rejoin its herd.
