PORTLAND, Ore., Aug 13 (Reuters) - A member of the Polish armed forces in the United States for training was found dead on Oregon's Mount Hood on Tuesday, two days after he told a roommate he planned to scale the peak, authorities said.
The body of Sebastian Kinasiewicz was spotted in an area that serves as a catch basin for debris, including rocks and ice, and it was believed the novice climber might have fallen around 1,000 feet, Hood County Sheriff's spokesman Pete Hughes said.
"We don't know when we'll be able to recover the body," Hughes said, citing conditions such as thawing ice in the area that could make recovery difficult. "This time of the year, climbing becomes extremely dangerous"
Kinasiewicz was reported missing after he told a roommate in nearby Washington state on Sunday morning that he planned to climb Mount Hood then failed to return the following day. His car was later found parked at a trailhead.
Kinasiewicz had been carrying crampons, an ice axe and a back pack with warm clothing and water, but no other survival gear, the Sheriff's office said.
Witnesses reported they saw a lone climber on a route called Cooper Spur on the north side of the mountain Sunday, said Mark Morford, a spokesman for Portland Mountain Rescue.
"That is a popular advanced route," Morford said.
Morford added that Mount Hood is the second most climbed glaciated mountain in the world after Mount Fuji in Japan. An estimated 8,000 people go up Mount Hood every year, mostly between April and July, according to the U.S. Forest Service.
Roughly two people die each year on the mountain and climbers are advised to file a route before leaving. Kinasiewicz's route was unknown.
The Hood County Sheriff's office said Kinasiewicz had been undergoing training in nearby Washington state conducted by Insitu, a company that designs and produces drone aircraft. It gave no further information about him, including his rank. An Insitu spokeswoman could not immediately be reached for comment. (Editing by Cynthia Johnston, Andrew Hay and Andre Grenon)
