One part of the Earth Science curriculum at Rice University was a geological techniques class, offering an introduction to describing, recording, and interpreting geologic features in the field, along with mapping and creating cross-sections. By far the largest project for this course involved mapping a spectacular sequence of rocks along the eastern edge of the Colorado Plateau, near San Ysidro, NM. During our week of field work, our class divided into small teams and hiked through Cretaceous, Jurassic, and Triassic sandstones and siltstones, learned how to recognize and record faults and deformed geology, and how to perform the variety of observations involved with producing a geologic map.

After returning to Houston, we spent the spring interpreting our observations and data. From these efforts, we produced our own, regional geologic map and cross section of the San Ysidro area, in addition to field methods report and a general geologic history of the Southwest.

This page showcases the final compilation I produced, including the geologic map, cross section, and unit descriptions. Below is a small collection of photos I took over the course of the trip.
