Lubbock Lake Landmark in Lubbock, Texas, preserves nearly 12,000 years of human use on the Llano Estacado within a meander of Yellow House Draw near former springs called Punta de Agua. Exposed after dredging in 1936, it became a major archaeological and natural history site whose layered geology records occupation from the Clovis period through historic times. Excavations have revealed extinct animals, butchering and toolmaking evidence, camps, hearths, a 5,000-year-old baking pit, traded pottery, and traces of Apache, Comanche, and early Anglo-American activity. Finds there also helped establish radiocarbon dating as a key method in Paleo-Indian archaeology.
