I currently serve as a principal geologist at the New Mexico Bureau of Geology & Mineral Resources at New Mexico Tech in Socorro. Much of my professional career has been based in field-geology studies of north-central New Mexico. My work in the Taos County area began in 1982, when I undertook a dissertation project on the geology of the Picuris Mountains. Since then, much of my field work has been directed toward completing a series of 12 geologic quadrangle maps that cover the Picuris Mountains, the Rio Grande corridor, and the Sangre de Cristo fault zone. During the last 10 years, I’ve been fortunate to team up with two USGS geophysicists, and cooperatively we have developed three-dimensional models of the structure and stratigraphy of the southeastern part of the San Luis rift basin. These models have proven to be essential for a variety of groundwater mapping projects in Taos County.
In 2011, I combined an enthusiasm for whitewater adventures with an interest in earth science education by publishing the book The Rio Grande: A River Guide to the Geology and Landscapes of Northern New Mexico, which won the a National Outdoor Book Award for best Outdoor Adventure Guidebook. I served as associate director of the Bureau of Geology for 12 years, managed the state’s Geologic Mapping Program for 12 years, and was program coordinator for the New Mexico Decision-Makers Field Conferences, a 10-year program designed to bridge the gap between earth scientists and policy makers. I have also been involved in training NASA astronauts in the Taos area since 1998.
