Education
- Adams State College, Alamosa, CO 1972-1976 - B.A. -- One of the coldest places in the US, known as the Land of the Cool Sunshine. ASU is a terrific small college. I took geology as a science credit at ASC and ended up majoring in geology and archeology.
- University of Arizona, Tucson, AZ 1976-1979 - M.S.--One of the hottest places in the US--The U of A was a real culture shock for me coming from Adams State, a school of about 2000 students, to a campus of over 60,000 students. I was lucky enough to get an assistantship, have a great thesis committee and an interesting thesis area looking at an early Cretaceous rudist patch reef near Bisbee, AZ.
Professional Experience
- Gretchen has worked at the New Mexico Bureau of Mines for 20 years
as a coal geologist. During this time, she has done field mappig in west-central
New Mexico, ran a drilling program for a 3-year coal
quality evaluation study in the San Juan Basin, and done numerous coal
resource evaluation studies primarily in the San Juan Basin. Developing
coal
databases has been a integral part of her work at the Bureau, and she
has had US Geological Survey cooperative grants for the past 20 entering
data into the National Coal Resource Data System. During the last four
years, Gretchen has been the principal investigator for three Coal
Availability studies, funded by the US Geological Survey, evaluating
coal resources using GIS. Other interests include looking at industrial
minerals associated with coal, such as humates, clinker and fly ash. As
part of the Bureau's outreach program, Gretchen has written articles on
coal geology and mining for Lite
Geology and has taught topographic map reading to teachers at Rockin'
Around New Mexico workshops. She has also been involved for several
years in Science
Olympiad running the Road Scholar Event.

Coal Companies Operating Mines in New Mexico:
There are now (Feb 2000) six operating coal mines in New Mexico. Three are owned by BHP, and two by Pittsburg and Midway. Five of the six are in the northwest part of the state in the San Juan Basin. The remaining mine is near Raton, in the northeast part of the state in the Raton Basin.Coal and Energy related links on the Web:
