Tyler Texas Geography, Geology & Terrain
Tyler is located in the geographical area of East Texas known as the "Piney Woods", about half-way between Dallas and Shreveport, and just south of the Interstate I-20 corridor.
Tyler, the county seat of Smith County, occupies an area of about 50 square-miles, and is at an official altitude of 544 feet (165 meters) above sea level. The terrain surrounding Tyler is mostly forested, gently rolling hills, dotted with ranches, lakes, and pastures.
Smith County spreads over 949 square miles of the East Texas Timberlands region, with two-thirds of this environment covered in post oak, blackjack oak, and tall grasses, and one-third is heavily forested with pine and hardwoods.
The soil varies from sandy prairie loams in the northwest and east to loam-covered clay through the remainder of the county.
The elevation ranges from 300 to 600 feet. Mineral resources include petroleum, natural gas, iron ore, clay, limestone, lignite, and salt. Less than 10% of Smith County is prime farm land.
