Horseshoe Canyon, formerly known as
Barrier Canyon, is in a remote area west of the
Green River and north of the
Canyonlands National Park Maze District in
Utah,
USA. It is known for its collection of
Barrier Canyon Style (BCS) rock art, including both
pictographs and
petroglyphs, which was first recognized as a unique style here. A portion of Horseshoe Canyon containing The Great Gallery is part of a detached unit of
Canyonlands National Park. The Horseshoe Canyon Unit was added to the park in 1971 in an attempt to preserve and protect the rock art found along much of its length.
