Description

Although much smaller, this crag is often confused with the Fourth Flatiron as the base is also within a few feet of the Royal Arch Trail. Climbing on this rock is unappealing as it sports a good crop of lichen. The summit of this rock is hidden in the trees south of the Hammerhead (which is quite a bit higher).

Getting There

Take the Royal Arch Trail to Sentinel Pass, and continue on the trail as it descends steeply for 100 feet or so. Soon after this look for a large angular block resting against the base of a rising ridge, this is Two Move Rock. Right after this you will pass within a few feet from the base of the Fourth Flatironette. Past here the trail ascends steeply, switchbacking under the south face of the Fourth Flationette.

To descend from the summit, scramble back down the south ridge (4th class) until it is easy to escape to the west on a ledge.
