Authorities have found the body of the pilot in a plane missing since Sunday morning.
A news release from Umatilla County Emergency Management said the plane crashed near Indian Lake, about 34 miles southeast of Pendleton on the Umatilla Indian Reservation.
There is no information yet about what caused the crash, and the news release said authorities also won't provide the pilot's identity until after notifying family.
The pilot was the only person in the plane, and the Umatilla Tribal Police Department is in charge of recovery.
According to an entry in the Umatilla County Sheriff's log, the pilot flew a green 1952 Bonanza V Tail from the Walla Walla Regional Airport in Washington at 9:30 a.m. Sunday to Enterprise. The plane, though, never made it there, and at 6 p.m., Umatilla County received notice it was missing. Earlier this morning, a Civil Air Patrol crew flying over the area spotted the crash.
