You can rappel from the top of the practice face down a bolted rappel line with a single 60m rope.
From the top, traverse carefully to the left corner of the buttress to a smallish tree with two rap-bolts by it's base. The bolts are hidden behind some rock, so it's tough to find. There is a tree with slings and rings about 20 feet above this rap station if you need to protect this approach (it is loose/slippery). Rappel on a single 60m rope to a second set of rap-bolts hidden next to the second large tree below. (-Larry S.)
