Sounds of the Wild West – An audio tour of Montana’s four major ecosystems

Like most of the West, Montana’s four major ecosystems are shaped and defined by water—either by water’s abundance or by the lack of it.

Dry, flat grasslands in the High Plains give way to a series of broad rivers in Upper Missouri. These rivers are fed by snowpack from mountain ranges in the Crown of the Continent. Their tributaries support an abundance of wildlife residing in the Greater Yellowstone ecosystem.
