Introduction On Highway 211, 0.5 miles south of Bandera Road, in San Antonio, Texas, is a road cut that was surveyed and studied by the students of the University of Texas at San Antonio, on October 31 st , 2011. The purpose of this study was to gain further functional knowledge of more in-depth geological work, to determine the road cut’s history, and to have an introduction to interpreting sedimentary rocks in a field environment. Standard methods and tools were utilized: hand lenses for examining rock characteristics, hammers for chipping away rock substrate, and simple observation of facies recorded in sketches. A Brunton compass was also used to determine orientations of surfaces. Stratigraphy Figure 1 depicts the rock cut. There are five units, and two main rock types, those being a yellowed “fresh” colored rock (possibly micrite) and a gray colored, weathered rock (possibly calcarinite and also micrite). Only the first three tiers were observed in detail, beginning with the bottommost layer in yellow, tier 1. Tier 1 has fairly thick strata, and is the only tier with a very distinct yellowing band, a probable fresh color very apparent. The rock type here that is dominant is presumably limestone, specifically, micrite, and the gradation is very crumbly. The sorting is very poor, and there are very
