Stone Holes (Mooring Stones)
"On the bank of the Pelican River, near the east end of the suspension bridge connecting Peterson and Sherwin Parks, lie three boulders into which have been drilled odd-shaped triangular holes. A nearby plaque proclaims them "Viking Mooring Stones." These stones–originally from the east shore of Grove Lake–are among many scattered across the Minnesota lake country and the Red River Valley. They are commonly believed to have been made by a wandering group of Norsemen, who reputedly used them to anchor their long ships while on a voyage of discovery into North America."
