Marion County sheriff's deputies are searching for a 21-year-old missing hiker in the Mount Jefferson Wilderness, officials said Sunday.



Riley Zickel, from the Portland area, arrived in the Jefferson Park area on Wednesday and planned to stay one night, spokesman Sgt. Don Parise said in a news release. He has not been seen since.

Jefferson Park is a subalpine meadow east of Detroit Lake. Camping there involves hikes of five miles or more into the backcountry.

Riley Zickel, 21, was last seen on Wednesday, July 27, 2016 when he went on a hike in Jefferson Park.



Marion County Search and Rescue, the Linn County and Polk County sheriff's offices, United State Forest Service and the Air National Guard are all searching for Zickel.



"We're hopeful we will find him today," Parise said Sunday.



Anyone with information about Zickel is asked to call Parise at 503-584-6276.
