Indian Creek (S81) is a Forest Service strip in Central Idaho. It's heavily used by outfitters taking folks on Salmon River rafting trips.

Here's the approach end of Indian Creek. Note how the runway approach actually curves down towards the river.
That's my preferred approach, as you can see that the direct approach has trees between you and the threshold.
The river approach requires a flare and a 45 degree turn at the same time, but has fewer obstacles.
Doug, Ceci and I visited the Indian Creek airstrip after a breakfast flight to Sulfur Creek.
