This arch lies on the Gemini Bridges Rd (4wd) which is
accessible either from UT 313 (road to Island-in-the-Sky)
or from US 191 in Moab Canyon. See "Trails Illustrated
Map/ National Geographic Map 500, Moab North" for
these alternate routes. Although it is not evident in the
photo, there is a narrow slot separating the two spans.
