The National Park Service says the body of boxing promoter Bob Arum's son has been recovered in North Cascades National Park.

Park spokeswoman Kelly Bush says 49-year-old John Arum's body was recovered Wednesday by a Snohomish County sheriff's office helicopter.

Arum, a Seattle environmental lawyer and avid mountain climber, planned a solo climb of 8,500-foot Storm King Mountain on Aug. 28. A search began Aug. 30 after he failed to return from the peak about 85 miles northeast of Seattle. After a five-day search, his body was spotted from the air at about the 7,700-foot level of the mountain's north face. A park spokeswoman said it appeared the experienced mountain climber had fallen.

Bush says poor weather and the difficult terrain delayed recovery operations.
