Lightning Dome is the first large granite slab one reaches when driving down Highway 13.

Park at a large pullout at mile 21.1. Cross the highway to a roadcut and scramble up a left trending ramp to the trail.

Descent
From the summit, walk on the uphill side of the two downed trees to the ridge crest, then head down the crest to the obvious stacked boulders. Continue down on their right to a pair of tall, slightly burned Ponderosa pines. Scramble down a bit of 3rd class terrain then left across a gully. Grassy ledges lead to the base of the Parasite Wall, where the approach trail leads back to the crag.
