Aquifers of East Texas

The Carrizo and Wilcox aquifers are the two major aquifers in the East Texas area. These rock layers are considered water bearing layers and so if you see them exposed you could possibly find a spring on your land.

The Wilcox Group and the overlying Carrizo Formation of the Claiborne Group form a hydrologically connected system
known as the Carrizo-Wilcox aquifer. This aquifer extends from the Rio Grande in South Texas northeastward into Arkansas and
Louisiana, providing water to all or parts of 60 counties. The Carrizo Sand and Wilcox Group crop out along a narrow band that
parallels the Gulf Coast and dips beneath the land surface toward the coast, except in the East Texas structural basin adjacent to the
Sabine Uplift, where the formations form a trough.
Municipal and irrigation pumpage account for about 35 percent and 51 percent, respectively, of total pumpage. The largest
metropolitan areas dependent on ground water from the Carrizo-Wilcox aquifer are Bryan-College Station, Lufkin-Nacogdoches,
and Tyler. Irrigation is the predominant use in the Winter Garden region of South Texas.

The fault trace is the intersection of a fault with the ground surface; also, the line commonly plotted on geologic maps to represent a fault.

Here are some geology photos I took of some rock outcrops between new harmony Texas and Ben Wheeler Texas : East Texas Geology photos

I like this picture of this rock because it shows some interesting lines
