Montana, the land of cowboys and the discovery of silver and copper during the 1880s, sits in the middle-top of the United States. I got to visit my brother who works in the Air Force in Great Falls, MT for the summer. Even though there wasn’t much to do around here, I was attracted by the Black Eagle Dam, which is this beautiful hydroelectric gravity weir dam located on the Missouri River in the city of Great Falls. I have visited this dam twice and is still struck by the size of it.
