As part of the Earth Science curriculum at Rice University, myself as well as other students mapped a spectacular sequence of rocks along the eastern edge of the Colorado Plateau, near San Ysidro, NM in March, 2015. During our week of field work, we traversed through Cretaceous, Jurassic, and Triassic sandstones and siltstones, learned how to recognize and record faults and deformed geologic units, and how to perform the wide variety of field observations required to produce a geologic map.
After returning from the field, 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.
Above is 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.
