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 wide area, this movement was in the hands of the miners rather than traders or other intermediaries. An unexpected benefit of the excavations at Mount Jasper was the discovery that workshops may yield three classes of artifacts, one of which, exhausted tools of exotic stones, holds valuable information about subsistence activities, the range of seasonal movements, and general cultural history. The mine, pits, and quarry workshops were located. The excavation procedures at the three sites, the mine and two workshops, are indicated.
