The Skamania County Sheriff's office says the body of Joseph Bohlig was found Tuesday, more than a day after the 52-year-old man tumbled 1,500 feet.
Bohlig, of Kelso, Washington, reached the summit with a climbing partner after a four-hour hike Monday.
Bohlig took off his backpack and a layer of clothing then decided to pose for pictures near the rim of the crater. He was backing up when the snow gave way and he fell.
Foul weather has hampered helicopter rescue efforts. Overnight temperatures overnight at the crater fell into the 20s.
