Once back on the main canyon floor after visiting Whitmore Arch, proceed up-canyon, scanning to your right (going up-canyon) about 40 ft. above the canyon floor for this arch, which has two openings looking like its namesake. You will be about a half mile from where the Ernie’s Country route crosses the wash leading to Whitmore Arch. The coordinates are UTM 12S 583341E, 4221413N WGS 84.
