Rangers suspended their attempts to recover the body of Colin Nathaniel Scott, 23, of Portland, Oregon.
“They were able to recover a few personal effects,” park spokeswoman Charissa Reid said. “There were no remains left to recover.”
Mr Scott had wandered from a designated boardwalk when he fell, in the latest in a string of incidents raising concerns over visitor behaviour.
He was with his sister and had travelled about 225 yards off the boardwalk on Tuesday when he slipped and fell into the hot spring in the Norris Geyser Basin, park officials said.
After his sister reported the fall, rangers navigated over the highly fragile crust of the geyser basin to try to recover his body.
Ms Reid said they halted the effort “due to the extreme nature and futility of it all” — referring to the high temperature and acidic nature of the spring.
