A 23-year-old man who walked off a boardwalk and slipped and fell into a hot spring at Yellowstone National Park has died, rangers said on Wednesday.

The man, Colin Nathaniel Scott, of Portland, Ore., had walked about 225 yards away from established trails near Porkchop Geyser on Tuesday. His sister saw him slip and fall into Norris Geyser Basin, a thermal feature at the park in Wyoming, and reported the accident, Yellowstone officials said in a statement.

Charissa Reid, a spokeswoman for Yellowstone, said in an email that “it was determined that there were no remains to recover,” and that the search for Mr. Scott’s body was suspended late Wednesday afternoon.

The episode is the latest example of visitors who have interacted with the park features or animals to sometimes disastrous results. In May, The Bozeman Daily Chronicle reported that a criminal complaint had been issued after three Canadian men strayed from trails and filmed themselves approaching the Grand Prismatic Spring. The men, who work for a company that films adventure videos, later apologized on Facebook and said they would donate $5,000 to the park.
