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.
Cascade County, Montana is located in the heart of the state and has a rich history that dates back to ancient times. The area was originally inhabited by several Native American tribes, including the Blackfeet, Assiniboine, and Gros Ventre. These tribes utilized the land for hunting, fishing, and gathering, and their presence left a lasting impact on the region.

In the early 1800s, European fur trappers ventured into the area, establishing trade relationships with Native American tribes. The Lewis and Clark expedition in 1805-1806 also played a significant role in the exploration and mapping of the region. The first permanent settlement in Cascade County, Sun River, was established in the 1860s, primarily for trading purposes.

The late 19th century saw the arrival of miners seeking gold and silver in the nearby mountains. The discovery of precious metals led to the establishment of mining camps and the rapid growth of towns like Neihart and Barker. The completion of the Montana Central Railroad in 1887 further stimulated economic development, fostering the growth of agriculture and helping establish Great Falls as the county seat.

In the 20th century, Cascade County experienced significant changes due to the development of hydroelectric power from the Missouri River. In 1910, the Rainbow Dam was constructed, followed by the Ryan Dam in the 1950s and the Gibson Dam in the 1920s. These projects not only provided electricity but also attracted industry to the area. Great Falls became a major center for manufacturing, particularly in the aerospace industry, with the establishment of the Malmstrom Air Force Base in the 1950s.

Today, Cascade County continues to thrive as a hub of commerce, industry, and recreation. It is home to a diverse population and offers a variety of outdoor activities, including fishing, hiking, and skiing. The county's rich history, from its Native American roots to its mining heyday and industrial growth, contributes to its unique cultural heritage and makes it a fascinating place to explore.
