Why us

Built different

Field seminars led by industry authorities who own their IP, backed by custom drone photogrammetry, digital field atlases and NREMT-led risk management. No legacy catalog markups, no post-trip surprise billing.

  • Led by authorities

    Every course is created and led by an independent geoscientist with decades in academia, industry or both. They own their IP and their science, and we vet them as exceptional teachers and communicators.

    More about us

  • Next-gen tech

    A suite of cutting-edge field gear for safety and efficiency, drone 3D models we fly and own, the Field Companion app, a digital Field Course Atlas and guidebook, and 3 months of web access.

    The science and tech

  • NREMT safety

    Founded and directed by a nationally registered EMT, with zero recordable incidents in over 38,000 exposure hours since 2019. Christopher or a seasoned, GFS-approved field leader is on site every trip, and we handle the logistics and paperwork so your people can focus on the rocks.

    How we run it

  • Capital efficiency

    Price, dates, inclusions, instructors and even sample flight costs are public, with our comparisons sourced and dated. On the four courses we compare, ours cost about a third less: $3,900 to $5,980 less per person. The price of six seats at Tetra Tech RPS covers ten of ours on West Texas.

    What it costs

  • Good neighbors

    Texas-based, and our founder is Leave No Trace certified. He volunteers with Texas Search and Rescue and the Houston Livestock Show and Rodeo, and E-Rocks, our geology-for-everyone project, is working toward nonprofit status.

    Giving back
