HOOD RIVER, Ore --- A soldier from Poland who had set out to summit Mount Hood on Sunday was spotted lifeless on the mountain Tuesday and presumed dead, officials said.
A National Guard Blackhawk Helicopter crew spotted Sebastian Kinasiewicz's body just after 10 a.m.
Crews said Kinasiewicz was likely hiking the Cooper Spur Route.
The search team found tracks near the summit that suddenly stopped, according to Sgt. Pete Hughes with the Hood River County Sheriff's Office.
Kinasiewicz decided to climb Mount Hood because several members of a military unit from Poland did so last year and planted the country's flag.
"He wanted to go up there and see that. That was his reasoning behind wanting to climb," Hughes said. "And if it wasn't there, then he was going to plant another one."
Hughes said it looked like Kinasiewicz had fallen more than 1,000 feet into a basin on the northwest side of the mountain.
Searchers said they won't be able to recover the body Tuesday, due to avalanche conditions.
"The spot where his body is at is extremely dangerous," Hughes said. "The helicopter crew was able to see boulders falling near the body."
The search for 32-year-old Kinasiewicz began on Monday, after his roommate reported him missing. He had an ice ax and crampons with him and was described as a novice climber, according to Hughes.
Kinasiewicz had been in in Oregon for training with drone manufacturer Insitu and went on the climb alone. His vehicle was found on the north side of the mountain, at the Tilly Jane Trailhead in Hood River County.
The roommate told the sheriff's office Kinasiewicz left around 8 a.m. Sunday to summit the mountain but never returned.
Kinasiewicz was married with at least one child, Hughes said. Websites in Polish say he was a warrant officer and had a background in photography . His work is displayed on a Facebook page dedicated to combat photography.
Insitu, based in the Gorge community of Bingen, Wash., issued this statement Tuesday afternoon:
We are extremely sorry to learn of the passing of our colleague Warrant Officer Sebastian Kinasiewicz. Our thoughts and prayers are with his family and friends during this difficult time.
