  1. Major roles of a geologist in support of NRCS programs. NPEG 2002 Geology #1

  2. Summary • Characteristics of geologists • History of SCS/NRCS • Roles of geologists within NRCS • Careers in geology Roles of Geologist in NRCS

  3. NRCS Geologists 1999 Roles of Geologist in NRCS

  4. GEOLOGISTSWhat are they like?? • Professional observers • Multi-dimensional thinking and visualization • Comfortable with uncertainty, trained to make scientific interpretations based upon limited information, “it depends…” • Intuitive • Time means nothing and everything! Roles of Geologist in NRCS

  5. Roles of Geologist in NRCS

  6. TOP TEN SIGNS YOU MIGHT BE A GEOLOGIST 10. You have ever had to respond "yes" to the question, "What have you got in here, rocks?" 9. You have ever taken a 22-passenger van over "roads" that were really intended only for cattle… 8. You have ever found yourself trying to explain to airport security that a rock hammer isn't really a weapon… 7. Your rock garden is located inside your house… 6. You have ever hung a picture using a Brunton compass as a level… 5. Your collection of beer cans and/or bottles rivals the size of your rock collection… Roles of Geologist in NRCS

  7. 4. You consider a "recent event" to be anything that has happened in the last hundred thousand years… 3. Your photos include people only for scale and you have more pictures of your rock hammer and lens cap than of your family… 2. You have ever been on a field trip that included scheduled stops at a gravel pit… AND THE #1 SIGN YOU MIGHT BE A GEOLOGIST: 1. You have ever uttered the phrase "have you tried licking it?” in the most professional sense possible. Roles of Geologist in NRCS

  8. GEOLOGISTSWhat do they do?? • “We help conservation districts to improve land and water use, to help them understand how to put land and water to the uses for which they are best suited. Our function is to interpret, extend, and apply to the purposes of agriculture the knowledge of geology.” • Paper for Colorado School of Mines, 1982, Dan Griswold, Portland NTC geologist Roles of Geologist in NRCS

  9. A little history of geology in the SCS • 1930’s: Dust bowl in southwestern Great Plains • 1935: SCS created by Congress, because “soil erosion is a menace to the national welfare”. • 1950’s: PL-566 and high geo-visibility Hugh Hammond Bennett, 1881-1960 Roles of Geologist in NRCS

  10. Chronosequence of Dam Construction in the United States From Before 1800 to 1993 Based on data in the National Inventory of Dams. Symbol size and darkness correspond to the size of the reservoir. Black and grey symbols correspond to dams older than the indicated time interval. Red symbols correspond to dams constructed during the time interval. Prepared by Robert Stallard US Geological Survey Boulder, CO 80303-1066 e-mail: stallard@usgs.gov Roles of Geologist in NRCS

  34. A little more history of geology in the SCS • 1960’s: Geo peak (about 130 geologists) • 1962: Silent Spring published • 1969: National Environmental Policy Act • 1970’s: Segue to environmental emphasis • 1985: Farm Bill • USDA program eligibility linked to performance • wetland identification • 1995: SCS became NRCS Roles of Geologist in NRCS

  35. A little more history of geology in the NRCS • 1990’s: We’re melting……….. • 2000: National Design, Construction, and Soil Mechanics Center staffed • 2001: three new geologists, and maybe more….. Roles of Geologist in NRCS

  36. Geologists roles within the NRCS • NEM 531 • Appropriate consideration of regional, local, and onsite geologic conditions is basic to sound conservation planning and engineering design in all NRCS programs. Roles of Geologist in NRCS

  37. Geologists roles within the NRCS • Engineering geology • Erosion and sedimentation • Ground water geology • Soil survey support • Contract administration • Geology training for field personnel • Professional relations • Cool stuff Roles of Geologist in NRCS

  50. Professional relations Participation in professional societies • ++++’s • Good meetings, nice locations, great field trips • Most meetings count as continuing ed. credits • Learn new technology, meetings and publications • Great network of contacts • If you serve as an officer or committee member • influence the direction of the organization • introduce newcomers to “the way we’ve always done it” • ----’s • Piles of publications, dusting Roles of Geologist in NRCS
