SILVERTON, WA - A 28-year-old woman from Seattle is missing in the Cascades, according to the Snohomish County Sheriff's Office. The woman was reportedly hiking a mountain that includes a rough scramble to the summit.

Around 1 a.m. Thursday, the sheriff's office received a call from the woman's boyfriend. He said that she had left for a hike at Vesper Peak around 8 a.m. Wednesday and was supposed to check in at 6 p.m. Volunteers and Snohomish County deputies searched for the woman on Thursday, but had not found her. Her car was found at the trailhead parking lot.

Vesper Peak is an 8-mile roundtrip hike east of Spada Lake. The hike is relatively tame until the summit, where hikers must scramble over loose granite. "It is mostly low angle rock, making a major fall relatively unlikely. This isn't to say there is no risk. Falls of 10-20 feet are certainly possible in places, and it's also possible to wander into parts of the mountain with greater exposure; but accidents and injuries here are rare," reads a description of Vesper Peak on the Washington Trails Association website.
