I have floated it from below Yankee Jim Canyon (the big white water stuff) to the town of Big Timber in Drift Boats, Rafts and a canoe. Once you get past Yankee Jim, the first 35 miles are fairly easily. As you get closer to Livingston, it gets a bit rockier. The next 20 miles or so will have some faster water and some big standing waves. Then the next 25 miles to Big Timber are again fairly easy going with some occasional fast corners. After that you are heading to North Dakota. Diversion dams and put ins/take outs few a far between. If you float it during spring and early summer run off, most of it can be nasty at times, with entire trees floating in it and a big volume of water. This year it didn’t start coming down until August.

In the mountains, all of our rivers are next to the highway with a train track running right next to it.  A river valley is the only place to squeeze that stuff in.
