Manning Fused Glass, a volcanic material that outcrops in a narrow east-west band near the southern limit of the Caddo Homeland just north of Huntsville, Texas. This material was used by local Caddo peoples to make stone tools. It is, however, characteristically fractured, as this piece is. It is also usually found in small nodules. This example is the largest known nodule of Manning Fused Glass, measuring about a meter across (39"). Photo by Ken Brown. |
