Chelan County sheriff Lt. Maria Agnew said the body of George Terry "T.J." Langley Jr. was found about 2:30 p.m. Saturday by searchers off the Clark Trail near Little Giant Peak.
Agnew said Langley was hiking in rocky terrain at about the 8,600-foot level and fell about 300 feet.
Langley left Sunday on a hiking trip with plans to be back Tuesday night. But he never returned and his family reported him missing Thursday morning.
More than 40 people spent Saturday searching for the 42-year-old, who is an experienced backcountry hiker. Helicopters were also brought in to assist in the search.
Other hikers in the area said they had seen Langley heading for Buck Mountain on Wednesday, but investigators said it was unclear when exactly he fell.
Bear attack survivor
Ten years ago, Langley survived a grizzly attack in Yellowstone National Park.
T.J. Langley is seen a week after he was attacked by a grizzly bear in 1999.
In an interview with KOMO News a week after that 1999 attack, he said he was hiking in the park when he ran across two grizzly cubs.
At first, he said he was excited to get a close up look at wildlife - until the mother bear showed up and attacked him.
Langley says the mother bear finally let him go - but not before mauling his back, head, scalp, eyes and ribs.
Langley said he held no grudges against the big bear. "She was doing her job as a mom," Langley said at the time. "She didn't have to be quite that good as a mom."
After the grizzly attack, Langley managed to hike four miles back to the trailhead, where he waved down passing motorists who called for help. He was then flown to a hospital in Idaho.
He told KOMO at the time that he would go hiking again - but he would never again go hiking alone.
