Need to get back to posting #geology here more⦠so here is an obsidian clast from a 16.1 million-year-old #rhyolite from Nevada (USA). Nice and fresh, found as a cobble in a creek.
Pics of an andesite shield volcano and Capulin cinder cone in the Cenozoic Raton-Clayton volcanic field, New Mexico (USA). Never been through here before, so it was nice to see, even at 70 mph. #geology#volcano#newmexico#igneous#sky
