Apple Island is a 37-acre nature sanctuary at the center of Orchard Lake. Owned by West Bloomfield School District, it has officially been called Marjorie Ward Strong Woodland Sanctuary since 1970. In 2018, the National Parks Service listed Apple Island in the National Register of Historic Places, recognizing its archaeological significance, and a boulder monument is installed on the island. The island's history extends from its formation during the recession of the region's last ice-age glacier to the presence of Native Americans to its inhabitation by various vacationers who eventually owned the island.
