Authorities are urging anyone visiting the Oregon Coastline to follow posted warnings, use extreme caution and be aware of the steep declines and rugged areas.
The warning follows the death of a 21-year-old Oregon State University student.
Family and friends of the woman are mourning her death after authorities said she fell 100 feet down a cliff at the Oregon Coast.
The accident happened on Sunday, May 19, at Neahkahnie Mountain, a popular viewpoint off Highway 101 near Manzanita.
investigators said Michelle Casey, of Happy Valley, climbed over a rock wall barrier to take photos when she tumbled down the side of the cliff.
As first responders arrived and repelled down the cliff they found the woman still alive but with life-threatening injuries. Rescue workers brought Casey back up the cliff and she was taken by a medical helicopter to a Portland hospital where she later died.
