The Gatehouse is a small, but good winter crag. It gets a lot of afternoon sun and is low on the mountain. There are 10 routes and they all require gear. 7 of them are 5.10 or harder. The quality of climbing makes it worth visiting, despite the difficult approach.
Getting There
Squeezing the Lemmon describes it pretty well. Go to the second major drainage past Molino Basin campground. As you go up the mountain, there will be a parking pull-off on the left just before this drainage. Walk up the drainage past a very tall formation on the right side. The Gatehouse is just past this and a little higher up. It is not very wide, but you will see bolts on it and a chimney on the left side. The approach is kind of a nasty bushwack so be prepared. It will probably take 30-50 minutes depending on many factors.
