	STS073-706-048 Canyon Lake, Texas, U.S.A. October 1995 Two different geologic provinces, divided by the Balcones escarpment, are apparent in this near-vertical photograph of the landscape between northeast San Antonio and San Marcos to the northeast--the gentle arc of the darker, elevated Edwards Plateau to the west and a lighter, more uniform landscape to the east. Interstate Highway 35 lies on the low rolling plains of the Black Prairie immediately east of the Balcones escarpment. Blue Canyon Lake is located on the uplifted, more resistant limestone of the Edwards Plateau to the west. The large white features along the eastern edge of the plateau are mines providing limestone for highways and building construction. White cumulus clouds appear east of the escarpment over the agricultural lands.
