It is a series of mountain ranges located in Montana, USA, renowned for its geological diversity and natural beauty. It is part of the Rocky Mountains and has a rich geological history, including ancient rock layers and diverse mineral resources. The geology of this region is mainly composed of sedimentary rocks, metamorphic rocks, and volcanic rocks, which record hundreds of millions of years of geological changes. The rock layers in the mountains reveal the sedimentary environments of ancient oceans, rivers, and lakes, as well as the subsequent processes of crustal uplift and erosion. These geological features provide valuable information for studying the tectonic activity, paleoenvironmental changes, and biological evolution of the Earth.
