Consulting Geologist and Hydrologist, Colorado Springs, Colorado.

Available for geologic consulting and contract work. (Professional Synopsis)


My geology work experience includes:

  • Independent consulting geologist.
  • University teaching at assistant and associate professor levels
  • Petroleum geologist for major oil company

Performed geologic (non-hydrologic) work in the following states and provinces:

  • Colorado
  • Wyoming
  • Montana
  • Nebraska
  • Nevada
  • Illinois
  • Saskatchewan, Canada
  • Alberta, Canada

The following content shows types of geology work that I have done, with one or more examples for each type. The list is not exhaustive and the examples are not all-inclusive.

Petroleum Exploration

    • Explored for petroleum in Colorado (Denver-Julesburg Basin, NW Colorado, Colorado Plateau), Wyoming (DJ Basin), Utah, Nevada, Illinois, Saskatchewan, and Alberta for a major oil company. This work included well log interpretation, reservoir mapping, surface and subsurface geologic mapping, stratigraphy, hydrodynamic analysis of petroleum systems, and well site operations.

Earthquake Hazard

    • Assessed earthquake hazard at a proposed mine site.

Slope Stability and Landslide Hazard

    • Served as expert witness on the effect of irrigation on landsliding and testified in court.
    • Assessed the stability of slopes near a proposed mine in a mountainous area.

Snow Avalanche Hazard

    • Assessed snow avalanche hazard along an access road at a proposed mine in a mountain valley.

Coal Resource Assessment

  • Assessed value of coal resources on a ranch.

Statistics in Geology

    • Performed statistical analyses of stable isotope data on methane from different geological provinces in California. Click here and go to "California Methane Stable Isotope Data Analysis."
    • Published paper on "Probability of Anomalies on Contour Maps" Ground Water, 8, 1970.
    • Performed a statistical analysis to see if sub-species of a fossil species were significantly different. (Honors thesis for geology bachelors degree.)

International Experience

  • Petroleum exploration in Saskatchewan and Alberta, Canada.
