Alibates Flint Quarries

National Monument - Texas

Alibates Flint Quarries National Monument is in Potter County, Texas. For thousands of years, people came to the red bluffs above the Canadian River for flint, vital to their existence. Demand for the high quality, rainbow-hued flint is reflected in the distribution of Alibates Flint through the Great Plains and beyond. Indians of the Ice Age Clovis Culture used Alibates flint for spear points to hunt the Imperial Mammoth before the Great Lakes were formed. The flint usually lies just below the surface at ridge level in a layer up to six feet thick. The quarry pits were not very large, between 5 and 25 feet wide and 4 to 7 feet deep. Many of these quarries were exploited by the Antelope Creek people, of the Panhandle culture, between 1200 and 1450. The stone-slabbed, multi-room houses built by the Antelope Creek people have long been of interest to the public and studied by archaeologists.

NPS Geodiversity Atlas—Alibates Flint Quarries National Monument, Texas Alibates flint deposits were used by indigenous peoples of the Texas Panhandle for thousands of years. The flint deposits are within the Alibates Dolomite, a marine unit within the Permian red beds of the Texas panhandle.

Russian knapweed (Acroptilon repens) is an invasive plant that has invaded the Southern Plains Climate Monitoring in the Southern Plains, Sonoran Desert, and Chihuahuan Desert Climate is one of many ecological indicators monitored by the National Park Service (NPS) Division of Inventory & Monitoring (I&M). Climate data help scientists to understand ecosystem processes and help to explain many of the patterns and trends observed in other natural-resource monitoring. In NPS units of the American Southwest, three I&M networks monitor climate using the scientific protocol described here. Kayaking across a fl ooded parking lot, Chickasaw NRA, July 2007.

In North America, the Paleozoic is characterized by multiple advances and retreats of shallow seas and repeated continental collisions that formed the Appalachian Mountains. Common Paleozoic fossils include trilobites and cephalopods such as squid, as well as insects and ferns.

In the American mind, the Southwest is a place without boundaries – a land with its own style and its own pace – a land that ultimately defies a single definition. Maize agriculture is one component of a general cultural definition of the Southwest.
