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.
Oscoda County, located in the northern part of the lower peninsula of Michigan, has a rich history dating back thousands of years. The area was initially inhabited by the indigenous Ojibwe, Ottawa, and Potawatomi tribes, who relied on the land for hunting, fishing, and gathering. European settlers began arriving in the mid-19th century, attracted by the abundant natural resources and opportunities for agriculture.

In 1840, Oscoda County was part of larger Mackinac County. As the population grew, the need for a separate county became evident. In 1881, Oscoda County was officially established and named after the Oscoda River, which flows through the region.

Logging played a significant role in the early development of Oscoda County. The abundant forests provided a source of timber for the booming lumber industry. Sawmills and logging camps sprouted up throughout the county, attracting migrants and laborers. However, by the early 20th century, the once-thriving industry began to decline, leading to economic challenges for the region.

Today, Oscoda County is known for its natural beauty and recreational opportunities. With thousands of acres of state and national forests, it offers ample opportunities for outdoor activities such as hiking, fishing, and camping. The county also hosts a number of festivals and events that celebrate its heritage, including the AuSable River Canoe Marathon and the Northern Michigan Lamb and Wool Festival. While small in population, Oscoda County continues to preserve its rich history and maintain its deep connection to nature.
