Empty Wheelhouse is the first route on the While Grotto Wall which is predominately limestone. The route overhangs about 12 feet in 50 feet. Your typical limestone pocket is mostly absent on this route.
the beginning is about 70 feet left of the biggest grotto.
8 bolts --- a zone above the grotto has some bolts in plates of limestone that do not sound well attached to the deeper solid rock. 2 of these bolt placements may require very long stock glue-ins. Hence, for now the climb is suggested as a TR problem.
