The Edwards Plateau is one of the largest source of chert in the United States. The Edwards limestone formation contains seams, ledges, beds and nodules of high quality chert. For example, on the north side of San Antonio, there are extensive expousers of Edwards chert, often fine grained grey to brown material, and there are many quarry locales where these were procured by ancient people of the region.
Information comes from "A Field Guide to Stone Artifacts of Texas Indians" by Tom R. Hester -and- Ellen Sue Turner. If you are a Texas collector this is a very good book.
This is a Kenny made of Tan Edwards Plateau chert .
This is a Friday made of Grey Edwards Plateau chert.
