San Antonio Map Art

The San Antonio River winds through downtown in a tight, deliberate curve, its path traced by the River Walk's tree-canopy below street level. The city spreads from this central spine in a loose grid, with five Spanish colonial missions strung along the river south of downtown like beads on a thread. IH-37 and IH-10 slice through the center, while the Edwards Aquifer's invisible boundary runs northeast to southwest, shaping which neighborhoods sit on recharge zones and which sit on contributing areas.
