Sullivan Creek

We hiked packrafts in and then hardshells and found a fantastic, very high-quality III/IV gorge. As of 5/9/26 it is very clean.

Nathan Johnson and I paddled part of the low-walled gorge on Sullivan Creek in the late-day baking sun after driving into the South Fork Valley. The South Fork Flathead at Twin Creek was 7,500 cfs. The creek was probably at a really nice flow for the whitewater, but felt pushy at that flow with the amount of wood. We found great whitewater and ran some quality Class III and IV but wood interrupted our run. Nathan was in his homemade ducky and I was in a kayak. We had not heard of prior runs but surely there were. The next day we kayaked Upper Twin Creek, followed by pack rafting Lower Twin Creek the following day.
