The topographic features of Lake County are the result of geological activity which began 150 million years ago when the Rocky Mountains were formed. Three million years ago, ice ages began in the northern Rockies which shaped the physical character of the land as it exists today.
The eastern part of Lake County is characterized by the steeply sloping west face of the Swan Range and the Mission Mountains.

Missoula is located in a deep valley surrounded by mountains and is cut by three major rivers, the Clark Fork River, the Bitterroot River and the Blackfoot River. The city is the namesake and center of the large, ancient Glacial Lake Missoula, which caused catastrophic floods across the northwest in the last ice age

They were formed during the Laramide Orogeny with the subduction of the Farallon Plate. This is a tectonic event that formed most of the Rocky Mountains and many other features along the western part of North America.
