Barr Creek Falls, is a waterfall located in the Rogue River Canyon within the Prospect State Scenic Viewpoint in Jackson County, in the U.S. state of Oregon. The waterfall is located at the south end of Barr Creek as it plunges into the Rogue River over a carved cliff surrounded by walls of petrified volcanic ash as a consequence of the Mount Mazama eruption. The waterfall has also been called Bear Creek Falls. The waterfall gets its name from the creek which was called Barr for the presence of a fence that prevented cattle from straying out of the local Red Blanket Ranch and that ran adjacent to the creek.
