The Fundamentals of Geology (Exam)
This week we take on the FG test — the Fundamentals of Geology exam — the very first step on the road to becoming a professionally licensed geologist. Jesse just sat the exam this past fall (yes, a geology professor going back to take Geology 101), and we get into exactly what that was like: the nerves, the cram sessions, and the very real fear of an embarrassing fail. We break down what's actually on the ASBOG FG exam — 110 multiple-choice questions across eight content domains, from general...

Granite Wars: The Debates That Built a Science
In this episode, we sit down with Dr. Mike Ackerson (Smithsonian) for the kick-off of a deep-dive series on granites and granitoids. This one goes into the weeds: the 250-year history of how arguing about granite shaped nearly every major idea in the geosciences. We trace the great controversies from the 1700s to today: 🌊 Neptunism vs. Plutonism — Did granite precipitate out of a global ocean, or crystallize from molten rock? How James Hutton's fingers of granite at Glen Tilt helped kill the ...

The Geologist's License: How the FG and PG Exams Get Built — with Keith Rapp
In this episode, we sat down with Keith Rapp, senior hydrogeologist, longtime volunteer with ASBOG (the Association of State Boards of Geology), and immediate past president of the organization. We dug into the professional geologist licensure process — what the FG (Fundamentals of Geology) and PG (Practice of Geology) exams actually test, how questions get written and vetted by panels of subject matter experts, why some states require licensure and others don't, and why Keith argues that lic...

What Makes Supervolcanoes? With Professor Shan de Silva and Dr. Rachel Phillips
What distinguishes supervolcanoes from regular or non-super volcanoes? How many supervolcanoes are on Earth today? What are the precursors to supervolcano eruptions? In today's deep dive, Dr. Rachel Phillips, from GeoGirl, and I we got to talk to supervolcano researcher, Dr. Shan de Silva, to answer all your supervolcano questions (and more)!

What is a Professional Geologist? An Intro to Licensure
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. Josh contrasts Canada and the UK, noting the UK’s Chartered Geologist is less central, while Canadian systems are province-based and may restrict the “geologist” title; Quebec lacks an academic carve-out and requires supervised experience plus an exam. They discuss rationales for licensure—public protection, minimum geology competency amid changing degree names, professional trust, insurance coverage, employability, and continuing education.

Visualizing the Deep Earth - CEO and Founder Christie Capper
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 led her to subsurface problems; mining research highlighted boom-bust cycles and long development timelines, motivating a broader focus on faster-feedback markets like water, geothermal, utilities, and construction. She discusses pre-seed funding, network-driven early hires, first paying customers, lessons on pricing and execution, and how investor rejection sharpened the company’s focus.

The Anatomy of Mountain Ranges
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; as we approach the range, we cross subtle, long-wavelength, low-amplitude folds that are often hard to notice without measurements; then we enter the fold-and-thrust belt where anticlines, synclines, and large thrust faults stack sedimentary packages and create dramatic ridges, valleys, and cliff faces (thin-skinned deformation). We explain how the growing mountain load flexes the plate to form a foreland basin that fills with sediment eroded off the range, typically thickening and coarsening toward the mountains. Farther inboard, we describe how erosion and unloading help exhume deep, high-grade metamorphic “roots” in metamorphic core complexes (gneiss, schist, and other intensely metamorphosed rocks), and how overthickened crust can later relax and extend, aiding exhumation. We also discuss how some mountain belts preserve suture-related features like ophiolite complexes, while others show subduction-related batholiths (e.g., Sierra Nevada, Idaho Batholith), and we note modern analogs such as the Persian Gulf foreland basin.
