  • The Anatomy of Mountain Ranges
    Feb 26 2026

    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.

  • Geology Meets Deep Tech - Danielle Bennett
    Feb 19 2026

    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 from corporate finance to FinTech and then into venture capital for about six years.

    They dig into what she’s learned from working with the geoscience community—friendly, non-confrontational, and highly opinionated—and why geoscientists may be slower to found startups (a strong perfection/excellence culture and highly localized expertise).

    Danielle breaks down “deep tech” in practical terms (asset-heavy and/or science-and-engineering-driven tech), why capital is moving earlier into deep tech, and how VCs are increasingly pulling innovations from universities and incubators. The conversation also gets into which geoscience-adjacent areas feel investable (like shallow geothermal heating/cooling, critical minerals, and renewables) and why groundwater can be harder to fund due to public-agency buying cycles and complex bureaucracy.

    Danielle closes by defining key funding terms—bootstrapping, debt financing, private equity, and venture capital—plus what VCs look for (why now, why this team, and scale) and common red flags (unclear messaging, weak grasp of numbers, and unjustified mega-rounds).

    We hope you enjoy this excellent interview!

  • Here Be Dragons - Exploring the Unknown with NASA Ames Chief Scientist for Innovation Dr. John Stock
    Feb 12 2026

    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 how cross-disciplinary collaborations could be the game-changers we need. Join us as we weave through tales of awe-inspiring geological discoveries and the frontier spirit that keeps the field exciting.

I don't know much about earth science but don't other planets have volcanoes too? what's significant about the andesite equivalent rocks?
