Lead Fillings is one of my favorite routes at Rushmore. To reach the route, scramble up slabs at the base of Child's Molar towards the obvious large chimney. Then descend slightly left to a small stance with a bolted line above it.
Follow the bolts (several, well protected) on the left side of the formation to a fixed anchor. Rap off with one rope off the back side.
Protection
bolts - not sure how many, but this climb is well protected
