Titre : Austin, Texas, U.S.A. October 1989
Description : (La description de cette image n'existe qu'en anglais)
Austin, the state capital, shows two different geologic provinces—the low, rolling Black Prairie to the east where agriculture and ranching predominate, and a dissected, uplifted plateau of limestone to the west. The Balcones fault, a northeast-southwest demarcation of these two geologic areas, creates the Balcones escarpment that extends through the western half of Austin. Visible are natural and manmade features—the southeast-flowing Colorado River along the southern edge of downtown Austin; dark, serpentine Lake Travis (bottom center); the runway of Bergstrom Air Force Base southeast of the city; and several white limestone mines north and south of the city and west of Interstate Highway 35.
