This two-sided map shows the geology that underlies bustling downtown Austin, Texas. Detailed descriptions of nine localities are provided on the reverse side. The map is a hand-drawn and painted rendering of the original environmental geology map by Garner and Young (1976). The view covers about ten square miles, from Barton Springs to the University of Texas campus. Sites can be reasonably reached by foot, bike, and auto. Sales proceeds help fund DTI's research and education efforts.
