Today on our way to Oregon Brett and I drove through the Coso Volcanic Field in Inyo County, California. These volcanoes were active in the #Pleistocene until about 45,000 years ago and left behind rhyolitic domes and basaltic flows like the ones shown here. #geology #volcano #roadtrip #roadsidegeology

@lts Hi Lucius thanks for turning me on to the Roadside Geology series. I just picked up a copy of Roadside Geology of GA from the library at the Marietta Square. It’s got entries on all the climbing crags in GA, and and also seeing interesting entries of geology facts in Atlanta itself, like Marta stations and old historic building with stone from local quarries…
