Mile Post Zero & Treaty Tree

Visit the site where Captain Thomas Cram placed the first marker of the survey point establishing the Wisconsin-Michigan state boundary in 1840. As part of the settlement of the “Toledo War” between Michigan and Ohio, most of the Upper Peninsula of Michigan was granted to Michigan for the “Toledo Strip,” which was granted to Ohio. He made a treaty for passage with Chief Co-Sha-O-Sha and his band of Ojibwa (Chippewa) near a large tamarack tree at the headwaters of the Brule River.
