I started my hike at the junction of the 4WD roads and followed for about 1.9 miles to the trail head, then another 0.25 miles to the arch. The road provides easy walking and the terrain seems to be dominated by Mormon Tea, another small shrub that I think is Blackbrush with a few scattered Utah Junipers and patches of Prickly Pear cactus.The Eye of the Whale Arch has a span of 37 feet, is 12 feet high, and 25 feet thick. Standing under the arch there is a slope going down the back side that looked easy enough to slide down, but might be tricky to climb back up.
Only 15 minutes of hiking pas the Eye of the Whale is the large Leaping Arch. There isn't a marked trail or a sign pointing it out, but it is visible from the Klondike Bluffs 4WD road. A 7 mile loop hike is possible by following the drainage beyond the sandstone fins southwest to the Willow Springs Road and then returning to the junction
