Dannemora, NY, Nov 08, 2011 — In the 19th century, iron mining was the main operation at the Dannemora Correctional Facility, with three main mines scattered within the structure's walls. The mines provided employment for the convicts and earned the region the nickname, "Little Siberia." Inmates also helped with prison construction and renovations. Coming up on the next Adirondack Attic, Andy Flynn and Adirondack Museum chief curator Laura Rice examine a photo taken during prison construction in the late 1800's.
