Hike into the main area of the Lower Satellites by following the signs to the Third Flatiron. Fifty yards after walking between the A-7 and BBC Boulders, look up to your right off the trail for a large boulder. Behind this boulder to the northwest are two 10 foot high boulders standing side-by-side.
Docking Mechanism ascends the south face of the right boulder. Using a high left hand sloping pinch/layaway on the corner and a miserable pebble for your left foot, launch up and connect with a sloping gaston 8 feet up. Anything less than the necessary body tension and you will barn-door off. Anything more and your foot will break free. From here move for several slopers at the top and pull over.
The gaston was buried under lichen. Seeing as there are no other holds, I have assumed this was a FA.
