Sharon Gay Buis, 48 and a physical therapist, was reported missing on the evening of Saturday, May 24, 2014, after failing to show for a planned morning hike with the Juneau Alpine Club. Her black Honda Civic was found parked and locked at the Mount Roberts trailhead on Basin Road later that day, and search dogs picked up her scent both near the parking lot and farther up by the tram, suggesting she had been on the trail.

A large coordinated search began early Sunday, May 25, led by Alaska State Troopers and involving Juneau Mountain Rescue, Southeast Alaska Dogs Organized for Ground Search, the U.S. Coast Guard, and many volunteers. Ground crews, canine teams and helicopters repeatedly scoured Mount Roberts and Mount Juneau but turned up no trace of Buis or her belongings. After four days the official search was suspended, although the investigation remained active and friends continued private searches, including explorations of abandoned mine shafts on the back of Mount Roberts in August 2014.

Investigators later reviewed interviews and searched her home; her overnight backpack and an emergency GPS were at the house, consistent with a planned day hike, and officers reported finding nothing to indicate foul play. The disappearance remains unsolved and a painful mystery for the Juneau community. Did anyone hiking Mount Roberts in late May 2014 see Sharon or notice anything unusual that day?
