Lubbock Lake Site has bone from the first Paleo-Indian period and was the main attraction in the Llano Estacado (Staked Plains) because it was the site of a major spring. The abundant water of the spring flowed out of the Ogallala aquifier and into the Yellowhouse Draw, a tributary of the Brazos River. There are incredible murals and diaromas of prehistoric life based on archaeological evidence at the Lubbock Lake Landmark Interpretive Center.
