An Eagle Creek-area woman died sometime during the night between Friday, April 18, and 7:20 a.m. Saturday, April 19, when a passing motorist discovered her in a creek.
Nanci Sue Garrison, 43, was negotiating a right curve in her 1988 Acura two-door northbound on Highway 211 just south of Estacada, when her car crossed the highway, and drove 15 feet down an embankment through heavy brush before coming to rest on its wheels in a creek.
Authorities found Garrison, who was not wearing a seatbelt, deceased.
Information indicates road conditions possibly were icy during the night.
Oregon State Police troopers from the Portland Area Command office are completing the investigation. Clackamas County Sheriff's Office, Estacada Fire Department, and ODOT assisted at the scene.
