This is a small crag with little to recommend it. I find it odd that this rock has 2 documented lines, while large solid rocks such as The Regency only have 1 published line....
But for the completest, it is still mandatory climbing.
Both routes are a little more heads-up than typical Flatirons climbing, as both are relatively untraveled and crumbly.
The anchor up top is presently cut through, but one can downclimb the 5.5 squeeze chimney on the North side of the summit to a simple scramble down to the ground. Odds are, that is also what you will climb up, as the East Face is a little hairy.
