Example Buttress Natural Arch
NABSQNO 12S-620207-4271054. Corona Arch is an old buttress natural arch eroded through a projecting wall of Navajo sandstone. The opening is a half-semicircular aperture (pie quarter shaped). It is considered old because weathering and compression strengthening have sculpted the lintel into a graceful half-catenary shape.
Corona Arch, which has also been known as Little Rainbow Bridge, is located in Bootlegger Canyon west of Moab, Utah. It is accessed via a marked trail of about a mile that starts at a BLM trailhead on state highway 279. This trail also leads by Gold Bar Arch and Bow Tie Arch, both good examples of pothole natural arches. Highway 279, which parallels the north bank of the Colorado River, is one of the most scenic highways in the US.
