Treadwell Historical Society – Treadwell Historical Society Our Mission The Treadwell Historic Preservation and Restoration Society was incorporated in 2008 as a 501 C 3 nonprofit entity to stabilize and preserve the remaining structures and foundations in the Treadwell Mine Historic Park in Douglas Alaska for the purposes of public access education and enjoyment. Our vision for this unique historical setting is to preserve for current and future generations the mine site and to make available for observation inspiration and enjoyment an accurate portrayal of the scale of the operation and the story that unfolded at Treadwell. The Treadwell Society will strive to maximize the potential of the Treadwell site to provide a coherent educational and interpretative experience that tells the story of the Treadwellan important piece of Juneaus history that has received little attention.
