There are now a pair of bolts with chains just east of the top of Sumo Greatness. Not the best place for toproping and sort of unnecessary, as there's plenty of anchor possibilities all over the place. Oh well. Hard to say how long they've been there.
Those anchors left of the slab are at the top of a climb called 22 Minutes till Closing (5.6) and are probably only suitable for toproping that climb. Sumo Greatness' anchor has a bolt and an open shut you could use for toproping. Ice Climb and Dean's List can be toproped off a tree.
