If you live in Ellis County and especially in the Ovilla-Midlothian area you realize the only main rock you find is white rock or chalk rock. Good for writing hopscotch on sidewalks and to consume for upset stomachs (a little natural cure that my geology teacher told me. I assume he knows what he is talking about.) Articles I've read about flint used by Indians in North Central Texas say that though some flint is found in the area, trading was another way they got it. I've read that there was much trading of goods between Indians of the Panhandle and North Central Texas Indians. Due to the lack of flint quarries in North Central Texas it appears that it was a valued commodity which the Panhandle seems to have plenty. The Alibate Flint has been traded all over the United States. An article by Wes Phillips says
"Other trade routes may have extended both north and south as seashells from the Gulf of Mexico and Catlinite pipestone from Minnesota have been found in the Antelope Creek villages. It is felt that many of the quarries were originally excavated by the Plains Village cultures. Certainly, these people were sedentary dwellers of the High Plains at a time when it is known that Alibates Flint was being traded in abundance. Furthermore, much flint is associated with these village sites, which indicates an intense use of the quarries at this time."Now we are talking mainly about pre-historic Indians.
Also the Handbook of Texas says
"The Alibates blades and quarry bifaces were used as trade items by the Panhandle Aspect peoples and were traded for Puebloan ceramics from the Rio Grande valley in New Mexico, obsidian from the Jemez Mountains in New Mexico, catlinite from Minnesota, and olivella shell from the Pacific coast. Frequently caches of Alibates blades or quarry blanks are found, but only a few are reported and described in the literature."Doesn't imply that Panhandle natives traded with the North Texas natives but they had a really good range of trade for their abundant flint. Those native people's Albiate quarries were like Arabians having all that oil. Everybody wanted and needed it.
I did here from an old timer that off of Joe Wilson Road South of it's crossing of Red Oak Creek there is some land that rises to a hill like "Indian Hill" but it was or is owned by the Gormans. Now back on their property on Red Oak Creek he said there is an outcroping of Flint. Would probably be a Honey Hole for artifacts. I took a picture of the private road (N 32degrees 32.610' W096degrees 55.534')that leads to the land up above. This property is probably in Midlothian but maybe Cedar Hill.
