Geography

The Metroplex overlooks mostly prairie land with a few rolling hills dotted by man-made lakes cut by streams, creeks and rivers surrounded by forest land. The Metroplex is situated in the Texas blackland prairies region, so named for its fertile black soil found especially in the rural areas of Collin, Dallas, Ellis, Hunt, Kaufman, and Rockwall counties.

Many areas of Denton, Johnson, Parker, Tarrant, and Wise counties are located in the Fort Worth Prairie region of North Texas, which has less fertile and more rocky soil than that of the Texas blackland prairie; most of the rural land on the Fort Worth Prairie is ranch land. A large onshore natural gas field, the Barnett Shale, lies underneath this area; Denton, Tarrant and Wise counties feature many natural gas wells. Continuing land use change results in scattered crop fields surrounded by residential or commercial development.

South of Dallas and Fort Worth is a line of rugged hills that goes north to south about 15 miles (24 km) that looks similar to the Texas Hill Country 200 miles (320 km) to the south.
