Melding Geology and Geophysics is our specialty.

Terralogos Geophysics is owned and operated by Clinton Colwell and was named for his training as a geologist and geophysicist. Clinton Colwell grew up in western Montana and graduated with Honors and a B.S. in Geosciences from the University of Montana. Clint then went on to earn a M.S. in Geophysics from Boise State University. He has performed a wide variety of geophysical work spanning a large range of ecosystems from the Alaskan tundra to the southern Indian Ocean.

Clint is versed in the acquisition, processing, interpretation, and reporting of numerous geophysical techniques as seen in our METHODS tab above.

At Terralogos Geophysics, helping you is our main goal. We strive to listen to your needs, integrate all available data into our work, and provide quality products on time and in a safe manner.

Clint loves to play on big cliffs, climb mountains, hunt wapiti with a bow, ski in the backcountry, pack horses in the woods, whitewater raft, and spend as much time outside as possible when not doing geophysics.
