Jesse and Dr. Joshua Davis introduce a new series on professional geology licensure, prompted by listener questions, exam study use of their podcast, and continuing-education approvals. Jesse shares starting the U.S. process by taking the FG (Fundamentals of Geology) exam and explains the typical U.S. pathway in 31 states: FG exam, geologist-in-training status, years of work experience under a licensed geologist (with some state-dependent education carve-outs), then the PG exam and references...

Today Jesse talks with Christie Capper, founder and CEO of Deep Earth, which aims to visualize the subsurface by digitizing and unifying scattered underground data into accessible 3D maps. Christie describes her path from a toy-inventor upbringing to studying economics and mechanical engineering (robotics) at Claremont and Columbia, then working at SpaceX, interning at the UN and Boeing, moving into early-stage VC in Europe, and joining a fusion startup. Work in carbon removal and geothermal ...

Chris is back!! Today we answer the simple question - Why do we see a predictable geologic and topographic progression as we drive from flat plains into mountains? We use examples from Michigan to Tennessee, the Canadian Rockies, Glacier, the Bighorns, Colorado, and the Appalachians to walk through a common sequence: we start on broad areas of mostly flat-lying sedimentary rocks (sandstones, shales, limestones) deposited in shallow seas, rivers, intertidal settings, and deserts; a...

On this episode of Planet Geo, we welcome Danielle Bennett—a startup operator with a venture capital background (and not a geoscientist by training) who’s been talking with tons of geologists, hydrogeologists, and engineers while helping build a geoscience-adjacent mapping company at Deep Earth Tech. Danielle shares how growing up with entrepreneur parents (who ran a groundwater-focused engineering firm) shaped her path, why she started a social-impact company in college, and how she moved fr...

In this riveting episode, we catch up with Dr. Jonathan Stock, Chief Scientist for Innovation at NASA's Intelligent Systems Division. We dive deep into the realms of geosciences and discuss how innovation can transform our understanding of the Earth and beyond. From quantum gravity gradiometers to AI-driven geophysical mapping, Dr. Stock reveals the tech that could redefine geospatial exploration. We also ponder why geosciences lag behind other fields in entrepreneurship and innovation and ho...

In this episode, we bring you a riveting Q&A session with GeoGirl Dr. Rachel Phillips and Dr. Joshua Davies, both experts in geology who explore the mysterious world of banded iron formations (BIFs). We dive deep into what BIFs are, when they formed, and their significance. Josh unpacks the debated origins of these rocks, discussing how they may be the most hotly contested rocks in the geological world due to our limited understanding of their formation process, despite their voluminous p...

In this episode, we are kicking off a new series on Geology News. We delve into why Venezuela is rich in oil, the complex tectonic interactions, and the geological formations that make it a hotspot for heavy, sour crude oil. We also take a humorous stroll down memory lane, reminiscing about our hard rock geology days and the unintuitive yet captivating world of sedimentary rocks. Join us as we explore why Venezuelan oil isn't just black gold but a treasure trove of geological intrigue. ...

To kick off Season 6 of the Planet Geo Podcast, we invited Doug Heller, a Penn State alum and geoscience finance guru, to explore investment risk in the geosciences. Doug shares thrilling stories about turning modest funds into substantial investments and offers invaluable advice for budding geologists and students. The episode delves into Doug's journey from exploring oil in the Gulf of Mexico to managing a complex bankruptcy case, and running Sun Specialty Products. Doug sheds l...

In this episode of Planet Geo, we dive deep into the fascinating phenomenon of petrification as we wrap up our season five re-release holiday series. From the beauty of petrified wood to its rare yet awe-inspiring occurrence, we explore how this natural wonder forms. We also tease exciting updates for season six, including segments with Dr. Rachel Phillips and interviews with top geoscientists. Strap in geologists and rock enthusiasts, because we're about to make some solid gains in your unde...

Welcome back to Planet Geo, the podcast where we delve into the wonders of our planet's geology, how it works, and why it matters. In this episode, part three of our holiday re-release series, we’re breaking down the basics of rock identification and collection techniques. Chris and I tackle the popular question: how do you identify rocks? We provide a general strategy perfect for budding rock hounds and outdoor enthusiasts. Plus, stay tuned for new episodes and exciting modifications coming ...
