The Jefferson is a very beautiful place to visit. It is a combination of three rivers, Big Hole, Beaverhead, and the Ruby. They all meet up in a small town called Twin Bridges, Montana. This river is well known for its really big trout. With an abundance of wildlife on the banks and plenty of trout to go around, the Jefferson is a must see river on any anlgers list. The best thing about going to the Jefferson is all the rivers in the valley are all in driving distance of each other.
