running 1:40:00 [2] 5.9 mi (16:57 / mi)
Colonnade Arch, aka 5-Hole Arch, plus an attempt to get to the Bowknot Bend overlook, which I didn't have time for. A sandy desert with sage & cacti & navigation is not the fastest conditions.
An hour or so of canyoneering Upper Twin Coral Box canyon beforehand.
