About Lake County
Lake County Timeline
Lake County, Minnesota has a rich history dating back thousands of years. Originally inhabited by Native American tribes, such as the Ojibwe people, the area was a part of their ancestral lands. These tribes thrived off the abundant natural resources of the region, including freshwater lakes, forests, and wildlife.
In the 17th century, French fur traders began exploring the area in search of valuable furs. This led to European settlement in the region, as fur trading posts were established along the North Shore of Lake Superior. However, the harsh climate and difficult terrain limited permanent settlement.
In the mid-19th century, Lake County experienced a population boom with the discovery of iron ore in the region. Iron mining quickly became the primary industry, attracting immigrants from various European countries, such as Finland and Sweden, who sought employment in the mines. The mining industry thrived for several decades, transforming the landscape and bringing significant economic growth to the area.
By the mid-20th century, however, the declining demand for iron ore led to the closure of many mines in Lake County. With the decline of mining, the economy shifted towards tourism and outdoor recreation. The scenic beauty of the area, including the iconic Split Rock Lighthouse, attracted visitors from across the country. Today, Lake County continues to be a popular tourist destination, known for its outdoor activities, beautiful lakes, and rich history.
