STS028-098-034 Temple, Texas, U.S.A. August 1989 Thin, linear Interstate Highway 35 (top to bottom) roughly shows the location of a dramatic geologic transition zone through this section of central Texas. West of this highway that generally parallels the Balcones escarpment, the landscape is one of uplifted limestone plateaus; east of the highway, the land becomes the grassy plains of the Black Prairie with numerous tree-lined tributaries flowing toward the Brazos River (not shown). East-west-aligned U.S. Highway 190 lies between Belton Lake (north) and Stillhouse Hollow Lake (south) and merges with Interstate Highway 35 at Belton. Northeast and southeast of this junction are Temple and Lake Granger, respectively.
