Archaeological excavations at Mount Jasper, a rhyolite source in northern New England, reveal that it was exploited at a slow rate over 7,000 years. Although stone from the mountain was transported over a broad region, its movement was in the hands of miners rather than traders or other intermediaries. An unexpected benefit of the work at Mount Jasper was the discovery that workshops may yield three classes of artifacts. One of these classes, exhausted tools of exotic stones, holds valuable information about subsistence activities, the range of seasonal movements, and general culture history. Archaeologists can no longer afford to overlook this rich source of data in their studies of stone-tool-using groups.
