The state of Montana was once home to a massive inland sea that covered much of North America around 80 million years ago during the Late Cretaceous period.
Rosebud County, located in the southeastern part of Montana, has a rich and diverse history. The area was originally inhabited by various Native American tribes, including the Sioux, Cheyenne, and Crow. However, the arrival of European settlers in the mid-19th century marked a significant turning point in Rosebud County's history.

In 1881, the Northern Pacific Railway constructed a line through the region, leading to the establishment of several towns, including Rosebud, Forsyth, and Colstrip. These towns quickly grew as settlers arrived in search of opportunities in ranching, farming, and coal mining. Rosebud County became known for its vast cattle ranches and fertile agricultural land.

During the early 20th century, Rosebud County witnessed significant development in coal mining. Large-scale operations were established in areas like Colstrip, contributing to the county's economic growth. The coal mining industry thrived for many years and became a major employer in the region.

In recent years, Rosebud County has faced various challenges, including the declining coal industry and the impacts of climate change. Efforts have been made to diversify the economy and explore new sources of renewable energy. Despite these challenges, Rosebud County remains a picturesque region with a blend of scenic landscapes, small towns, and a rich cultural heritage.
