Welcome to our 51st edition of Lite Geology! Lite Geology 51 explores the San Juan Basin in the Four Corners area of northwestern New Mexico. Kevin Hobbs, New Mexico Bureau of Geology and Mineral Resources (NMBGMR) Field Geologist, lets you ride shotgun on a geologic road tour of the San Juan Basin. Geologist Kate Zeigler, owner of Zeigler Geologic Consulting, LLC, describes her work with Navajo Technical University (NTU), Navajo Transitional Energy Company, and Navajo Nation schoolchildren to excavate “Little Foot,” a Late Cretaceous Period Alamosaurus. Our NMBGMR Mineral Museum Curator Kelsey McNamara provides an overview of San Juan Basin concretions for our Earth Briefs segment. Virginia McLemore, Senior Economic Geologist, shares her research on utilizing San Juan Basin coal and coal fly ash as a source of rare earth elements. Geochemist Bonnie Frey discusses the role of the NMBGMR/New Mexico Tech (NMT) partnership with NTU to use water filtration technology as a teaching tool for NTU students and as a way to improve water quality for the Navajo Nation. And lastly, our Through the Hand Lens series focuses on Talon Newton as he discusses his work as an NMBGMR hydrogeologist and his research on the effects of the 2015 Gold King Mine spill on the Animas River.
