Lower Thompson

Spring Flows below Little Thompson River Bridge (West side)

You should see it at 1,200 or even 2,000 it gets even more fun.
I think that around 2,000 it warants a class IV, and is much faster and pushier with a few log jams to avoid. It is a blast, and one of my favorite rivers in western MT. Also it can be a great warmup for Prospect Creek which is just the other side of T Falls.
