From Stanley, Idaho, go about one mile West and cross the river. Walk up onto the bluff to the North.
This is near the headwaters of the Salmon River, which is a few miles away, about where the sun is setting. I have always been fascinated by winding rivers, and was amazed at the beautiful design it made after I climbed on a high bluff so I could look down on the river. I waited and was able to also get the setting sun as well.
