This was found in the panhandle by the Salt Fork Red River in Wellington, TX
Collingsworth county. I'm thinking it's maybe a Calf Creek/Andice variety?
The material is Tecovas Jasper. The Tecovas Formation is a geological formation in Texas that contains a high-quality natural tool stone resource. This material originates in the late Triassic Tecovas Formation, is widespread along the eastern Caprock Escarpment of the Llano Estacado, and in the Canadian River valley west of Amarillo.
In general, Tecovas jasper is a fine micro-crystalline material similar to Alibates in texture and color. It is distinguishable by its often variegated or mottled appearance, with some exceptions. Most pieces are red, brown, cream,white, yellow, or green in colors. It is opaque, often with bluish white quartz vugs. It occurs in massive boulders as much as a meter in diameter that also contain tiny quartz-filled vugs. Both Alibates and Tecovas jasper come in red, but the latter has a more even red, and is generally mottled or variegated often with tiny quartz vugs. The jasper isusually visually distinguishable from Alibates, but some pieces may look quite similar to it. Both Alibates and Tecovas jasper reveal very dark or purple/velvet ultraviolet light response.
A concentration of small outcrops of theTecovas Formation lies between the town of Quitaque and Palo Duro Canyon in the Texas panhandle. This concentration is the best-known area for Tecovas jasper. Tecovas Formation outcrops are also known to occur along the Canadian River valley in the western half of the Texas panhandle. In spite of the fact that the Tecovas Formation is visible in a valley wall setting, this does not mean that jasper is present. The Tecovas Formation is also recorded in West Amarillo Creek valley, including the nearby Wildcat Bluff Nature Preserve just north of the project area. Other known Tecovas outcrops/source areas are scattered around the Amarillo region and include an outcrop at the South Basin quarries (Rotten Hills quarries) 24 km south of Landergin Mesa in eastern Oldham County; an outcrop at Coetas Creek at the southern end of Lake Meredith; several small outcrops along Blue Creek north of Lake Meredith in Moore County; and an outcrop in West Amarillo Creek. The small outcrops in the Canadian Breaks are not well known and have not been systematically investigated or reported. Multiple sources are undoubtedly present and exposed within the Tecovas Formation outcrops across the Canadian Breaks along the Canadian River valley west of Amarillo, but these are, as yet, unrecorded. A small Tecovas outcrop is also reported in the Oklahoma panhandle along some small tributaries of the North Canadian River.
Tecovas jasper has been visually identified in sites dating from Clovis and Folsom times, such as Blackwater Draw Locality No. 1 in east-central New Mexico and the Folsom site in northeastern New Mexico. This lithic material was likely used throughout prehistory. The presence of archaeologically derived Tecovas jasper in east-central New Mexico, some 250 km southwest of Landis property, also indicates the transport of thishigh-quality material across the landscape by the prehistoric po****tions. Caches of Tecovas jasper are infrequent, but a few have been reported, such as the Mackenzie, Palo Duro, and Crump Farm caches. The Mackenzie cache is an isolated pit about 60 by 250 cm in size and about 45 cm deep. It contained minimally 666 non-cortical flakes, the longest of which is 10 cm in length, though most are 3– 4 cm long. Patrick S. Willey and Curtis D.Tunnell thought the cache pit represented an episode of heat treating the jasper rather than a storage pit.Tunnell reports that one of the Witte caches near Palo Duro Canyon consists of 608 unworked flakes of Tecovas, similar to the Weaver-Ramage cache. The Crump Farm cache in Motley County includes bifaces and flakes of Tecovas jasper. These caches are all within the region, indicating that Tecovas materials were generally not widely distributed. The Turkey Creek cache contains “four oval bifaces pointed at one end measuring 11–13 cm long and 8 cm wide, four relatively long blades, two biface thinning flakes,and a large, oval bifacially shaped quarry blank weighing some 1.36 kg (3 lbs.)”. None of the caches have been radiocarbon
great find---to me the material looks like tacovis jasper from the texas panhandel. i don't think it is a ouachita. the few ouachita knives i have seen don't have long drooping ears. location of the find seems way to far west for a ouachita. oh did i say great find? great find!!!
