The rock appears to be a metabasalt or gabbro from the north. The rock is alongside the trail that goes from Tamanowas Rock to the northeast side of Anderson Lake. Easy access from the parking lot at Tamanowas Rock. About a 1.5 mile roundtrip, 2 hours plus you can see Tamanowas Rock, which is an adakite.
