Bexar County, in the interior belt of the Coastal Plain of South Central Texas, is crossed by the Balcones Escarpment. The area northwest of the escarpment, about one-eighth of the county, lies on the Edwards Plateau in high, hilly country, the source of numerous springs and artesian and underground wells. The San Antonio River and San Pedro Creek originate in such springs. Bexar County comprises 1,248 square miles. The county seat and largest city is San Antonio.
