Sounds like he was committing suicide although I don’t want to put a spin on it that isn’t true.
He walked 225 yards to the area. That’s a quarter of a mile. Seems pretty determined to get to the area.
I would imagine the area was steaming and blowing hot water. Says “Norris Geyser Basin is the hottest and most changeable thermal area in Yellowstone,” and at the bottom of the article it says “a teenage boy and his father suffered thermal burns near the Castle Geyser. They were flown to Salt Lake City for treatment”.
Half of a quarter of a mile.
No matter. He's still dead.
Hey now, didn't you recently claim your pickup does a 9.5 sec quarter mile? That explains it! (No offense!!! :-))
