Selected Western Maine and Eastern New Hampshire indigenous lithic (rock) types, will be discussed, from the book Indigenous Lithic Sources of Northeastern North America (ILSONENA), 2016, by Mark Brockmann & Barry Keegan. Lithic replicates (arrowheads, knives and stone tools) created by Barry Keegan for the ILSONENA book, will also be displayed. The archaeology/geology, physical properties and occurrence of the Maine and New Hampshire lithic types, will be discussed during the presentation. The presentation will focus on those lithic types found in the Rangeley Lake Region of Western Maine. Participants are invited to bring in personal lithic specimens/artifacts for identification/discussion, and to participate in the discussion.
