This is a great new boulder with routes on the east, north, and west faces. The problems range from V0 to about V5? This is a very secluded area, and the rock is good but could still use some cleaning.
Hike west up the trail from the Tomato Rock for about 100 yards and then head northwest for another 30 or so yards. Find an flat area that looks like an old road and head west for a bit. You will come to El Primero Boulder on the left and The Annex Boulder just down the hill. The Third Flatiron is straight ahead of you.
