These points are made on a variety of stone materials, including chert, yellow-brown jasper, and gray or gray-blue striped rhyolite, as shown in these examples. Since jasper and rhyolite do not occur geologically in our area, these raw materials must have been "imported" through prehistoric trade networks from southeastern Pennsylvania.
Susquehanna Broadspears are found in a range of sizes. The smaller points may actually have been spearpoints, but the large examples-- up to 6 inches long-- were probably used as knives. It's also not unusual to find examples with the edges resharpened to a concave outline and to find points reworked into drills.
