About Thomas Simonseth's case

Primary Source: King5

According to King5,

MARBLEMOUNT, Wash. — Search and rescue crews are looking for an overdue hiker east of Marblemount in the North Cascades. Thomas Simonseth, 66, of Mount Vernon planned to hike the Hidden Lake Trail on Saturday, May 22, 2021, but didn’t return home by 7p when he was expected, according to the Skagit County Sheriff’s Office.

Friends with mountaineering experience hiked in the area to search for him but weren’t able to find him, according to the sheriff’s office. They spent the night in the area hoping to continue their search in the morning. The sheriff’s office and multiple county and municipal search and rescue groups began their official search for Simonseth on Sunday morning, May, 23, 2021.

Simonseth wasn’t found Sunday, and the groups are expected to continue their search Monday. Since it is an active search, the sheriff’s office urges the public to not look for Simonseth.
