how did geography influence the way indian tribes in texas lived
Coahuiltecan people Although living near the Gulf of Mexico, most of the Coahuiltecan were inland people. Near the Gulf for more than 70 miles (110Â km) both north and south of the Rio Grande, there is little fresh water. Bands thus were limited in their ability to survive near the coast, and were deprived of its other resources, such as fish and shellfish, which limited the opportunity to live near and exploit coastal resources.
