Grassroots Activism and the American Wilderness: Pioneers in the 20th Century Adirondack Park Conservation Movement, a new exhibit featuring material from the John S. Apperson and Paul Schaefer collections, will be on display in the Lally Reading Room of Union College’s Schaffer Library through December.

The collections, spanning from 1899 to 1996, provide a window into the history of the American environmental movement and the tensions that erupted over efforts to conserve the Adirondack Forest Preserve and expand the Adirondack Park. The materials also give a broader understanding of the history of national park and wilderness preservation and the critical role activism played in those efforts.

The Schaffer Library is located at 807 Union Street, Schenectady.
