Geologic Field Camp: Blooming and In Tents, Lumping and Splitting

     Ah, nostalgia for geologic field camp and geologic field work emerges in the springtime like saguaro cactus blooms and ocotillo flowers!




     Gearing up for 6-week or longer treks into Arizona, Mexico, Arkansas, and Nevada included these sorts of checklists (minus the computer in the 70's and 80's):




      We've discussed some field gear including rock hammer and Brunton compass here at PEOTS before:



         Other additions include tape measures, notebooks, chisels, rock bags, and markers. At the heart of every geologist's field record is the field notebook, made of carefully-stitched waterproof paper which notes cross-sections, sample locations, and other field observations tied to aerial photographs, LANDSAT images or Geographical Information Systems (GIS):



       It's a dense, "chucky-jam-full" source of information about every day in the field. Entering data and observations into an electronic tablet or Smartphone doesn't have the same thrill for me. I recall making every inch of every page count. . .These notes, especially cross- sections are geological works of art.



      One of my most memorable experiences was comparing my Paleozoic era cross-section with a dozen or more units to the cross-section from a geological engineer at field camp. His read "rock" or "bedrock" for the entire cross-section!

       Are you a lumper or a splitter?

Happy almost spring from the latter,
