location
Along Hwy 190 west of Panamint Springs. Death Valley National Park (Inyo County, California, US)notes The dark rocks exposed here are olivine basalt. formed during the late Pliocene about 4 million years ago. Basalt flows emerged from many feeder dikes like this one and covered hundreds of square miles in this area. The flows are well exposed along the flanks of the Argus Range and the Panamint Range. However, most of the feeder dikes are hidden beneath the flows. This dike cuts through an older Pliocene fanglomerate composed of somewhat rounded fragments of Paleozoic rocks deposited in a range-front alluvial fan.keywords: geology, earth science, volcanism
