Sometime in the morning of a bluebird August day, a Seattle woman picked up a pencil and wrote her name on the register at a trailhead off the Mountain Loop Highway. The paper is there to log the hikers on Sunrise Mine Trail #707, a route that winds to the top of Vesper Peak. Her scrawl is the last concrete sign of the 27-year-old day hiker whose disappearance launched one of the biggest search and rescue operations in the state’s history.
