Mesa Arch, in the Island in the Sky District of Canyonlands National Park, formed as surface water pooled and eventually eroded through bedrock at the mesa’s edge. As the sun rises, its rays reflect off the 800-foot-high cliff of Jurassic-age sedimentary rock below the arch, bathing the bottom of the arch in an orange glow.
