The town of Libby, Montana, was the site of one of the worst environmental disasters in US history, when it was discovered that vermiculite mined from the area was contaminated with asbestos. The contamination led to widespread illness and death, and cleanup efforts have been ongoing for several decades.
Lake County, Montana, located in the western part of the state, has a rich history that dates back thousands of years. The area was originally inhabited by Indigenous peoples, particularly the Salish and Kootenai tribes, who called it home for centuries. These tribes had a deep connection with the land and water, relying on the abundant resources for their sustenance and cultural practices.

In the early 1800s, European settlers began to explore and settle the area. The first recorded non-native explorer to visit the region was Canadian fur trader and explorer David Thompson in 1809. However, it wasn't until the mid-1800s that permanent settlement began. Missionaries and miners were among the first to establish settlements, drawn by the area's natural beauty and resources.

The establishment of the Fort Missoula Military Reservation in 1877 played a significant role in the development of Lake County. This reservation was created to protect settlers and control the Native American tribes in the area. However, tensions between the United States government and the Indigenous tribes eventually led to the Allotment Act of 1904, which caused the loss of much Native American land.

Throughout the 20th century, Lake County continued to grow and develop. Agriculture played a crucial role in the economy, with farming and ranching becoming prominent industries. Tourism also began to thrive due to the area's breathtaking landscapes, including Flathead Lake, the largest freshwater lake west of the Mississippi River.

Today, Lake County remains a vibrant and diverse community, attracting visitors from all over the world with its stunning natural beauty and rich cultural heritage. It continues to be an important hub for outdoor recreation, agriculture, and Native American culture, offering a unique blend of history and modernity.
