Join us for a cartographic celebration of 100 years of our national parks. Come and explore the varied and vast landscapes and monuments protected by the National Park Service. We'll feature 19th century maps of Yosemite and Yellowstone, as well as one of Michigan's own national parks, Isle Royale.

Third Thursday is a monthly open house that highlights items from the Clark Library’s vast map collection. These fun, thematic events are open to everyone, offering the community a look at some of our favorite maps and other materials.
