Michigan is the only state to have two designated "state stones": the Petoskey Stone, which is the state stone of Michigan, and the Isle Royale Greenstone, which is the state gemstone of Michigan. The Petoskey Stone is a fossilized coral that is found primarily in the northern Lower Peninsula, while the Isle Royale Greenstone is a rare mineral found only on Isle Royale in Lake Superior.

Presque Isle County, located in the northeastern part of Michigan's Lower Peninsula, has a rich history that dates back centuries. The county's earliest inhabitants were Native American tribes, including the Ojibwa, Ottawa, and Potawatomi, who inhabited the region long before the arrival of European settlers. These tribes relied on the area's natural resources, including the dense forests and abundant wildlife, for sustenance and trade.

European exploration and settlement began in the 17th and 18th centuries, with French fur traders venturing into the region. The area witnessed increased exploration and the establishment of trading posts in the early 19th century, as the fur trade industry expanded. In 1836, Presque Isle County was formally organized by the Michigan territorial legislature, making it one of the oldest counties in the state.

The county's development was greatly influenced by its natural resources, particularly timber and limestone. The abundance of beech, birch, and maple trees led to the establishment of logging operations, which played a significant role in the economic growth of Presque Isle County in the late 19th and early 20th centuries. The County also became known for its limestone, which was quarried and used for construction and various industrial purposes.

Presque Isle County's economy later diversified, with an increasing focus on tourism and recreational activities. With its picturesque shoreline along Lake Huron and numerous inland lakes, the county became a popular destination for fishermen, boaters, and outdoor enthusiasts. The area is also home to the Presque Isle Lighthouse, built in 1870, which has become a historical landmark and tourist attraction.

Today, Presque Isle County continues to thrive as a recreational paradise and a close-knit community that values its rich history. The county's residents take pride in preserving its natural beauty and heritage, making it an inviting place for both residents and visitors to enjoy.
