Authorities cleared multiple fake $100 bills off Oregon’s Multnomah Falls on Saturday, urging hikers not to risk their lives for false allure, according to the Multnomah County Sheriff’s Office.

The fake Benjamins, 15 in total, were spread “30 feet over the edge of the falls,” the sheriff’s office wrote on Twitter. Portland Mountain Rescue members collected the bills in a rappelling operation.

“Why they would want to get off the trails to do that themselves and put themselves at risk,” visitor Tommy Griffin told the outlet.

Griffin further wondered “why they’d want to put someone else at risk.”
