One night as the shop owner worked late hanging things, a hammer was laid down to grab something; but when the shopkeeper went to grab it again, it was gone! Knowing the ways of prankster spirits, the keeper demanded the return of the hammer by scolding the spirit and magically it reappeared! The trickster like occurrences led our source to believe the spirit of a small child inhabits the shop.
This claim seems to be corroborated by Robert Chamberlin, the founding member and president of Northwest Paranormal Investigations, a group that seeks out and documents strange activity in the Pacific Northwest. Mr. Chamberlin has investigated the Klondike Restaurant (71 S. 1st Street) and has found paranormal activity throughout the old hotel. "One upstairs room in particular was striking in that his team had sensed a feeling of death. It was very strong and more than one person picked up on it... We took photos and had some spirit orbs on them. We were later told that a gentleman had died a tragic death in that room."
Other paranormal hotspots include the high school auditorium called "The Old School" in St. Helens, which is haunted by a woman named Vera who died there and has been seen messing around in the lighting booth. The site also lists the Kinder Cemetery, located on the north side of Highway 30, which is inhabited by an old ghost named George who when angry has been known to push and slap people!
