The 132-year-old piece of history was discovered by a survey crew. Workers believe the rifle has been standing there the entire time. "The cracked wood stock, weathered to grey, and the brown rusted barrel blended into the colors of the old juniper tree in a remote rocky outcrop, keeping the rifle hidden for many years," the park wrote on their Facebook page.

KSL reports the serial number was still visible allowing historians to find it was made in New Haven, Conn, and shipped in 1882. Records don't show who bought the Winchester.
