In Montana, marks of old civilization are everywhere. As a magaine interested in places that are hard to get to (and harder to make a life in), we were drawn to Montana's ruins. Big Sky country is an unforgiving locale that demands hardiness from its inhabitants, so it makes sense that signs would abound of those who didn't make it. Below, find a gallery from our intrepid explorer and friend, Kevin Russ, who dispatched himself to several lost cities in Big Sky country—including Elkhorn, Nevada City, and Bannack. These ghost towns are all that remain of old settlements that succumbed to the elements, disease, or simply an evaporation of money.
