As you're approaching the West Buttress area of El Cap there's a short downhill section just before the 3rd class with fixed lines. Just before this downhill section you will see an obvious 60ft tall flake on the wall above. It sits atop a ledge system about 30 or 40ft above the ground. This ledge can be access by some grassy 3rd class stuff over to the left or you can climb a direct start up the face directly below the Left Side route. This direct start is unprotected by basically amounts to a 30ft 5.6 bouldering problem.
Anyways the left side route starts up some flakes and stuff with sort of iffy pro. The climbing isn't hard though, as long as nothing breaks on you. Overall the climbing easier than it looks thanks to some good features on either side of the corner and after the first 20 ft you get some good pro. This climb can be a fun warm up for some of the harder routes in the area.
Rap with one rope from a bolted anchor at the top of the pinnacle. The bolts at the anchor are good.
