Most of the geologic mapping for this study has been accomplished on air photos and has been transferred to the topographic base map. The main emphasis now is to process and interpret the geologic information as it is added to this website. This work will continue indefinitely. The primary future opportunities will likely be the result of observations and insights that emerge as the analysis and interpretation are accomplished. It is also possible that more quadrangles – in addition to the companion San Marcos North companion website –may be added in the Austin–to–San-Antonio growth corridor.
