Shirley Baumann, 61, disappeared from the North Bend area of Washington after setting out alone on a planned solo camping hike on July 20, 2020. Her son dropped her at the Quartz Creek Trailhead; she intended to reach Lake Blethen and return on July 22. She is described as 5 feet 4 inches, about 145 pounds, with blond hair and hazel eyes, and was believed to have been carrying brown sunglasses, reading glasses, and a basic cell phone.

Searchers found her car at the trailhead and scent evidence led dogs to her campsite, where her hiking and camping gear was located but Shirley was not. Volunteer search and rescue teams logged over 3,000 hours searching difficult terrain in the Snoqualmie River Middle Fork, an area with many large cliffs; after several days the ground search was suspended and helicopter searches continued. The discovery of her belongings with no other clue has left her disappearance unresolved.

Did anyone in the North Bend area see Shirley on or after July 20, 2020, or have information about her planned route to Lake Blethen?
