The site now known as the Confluence Overlook is interpreted at a highway pullout over looking the confluence and valleys of the Snake and Clearwater Rivers. The pullout is about 8 miles north of Lewiston, Idaho, on the Lewiston Grade of U.S. Highway 95. The scene is dominated by a rolling grassy foreground that slopes steeply down to the Clearwater River, more than a thousand feet below. A sense of the confluence area and the scale of the surrounding uplands -- part of the Nez Perce homeland -- can be gained from this vantage point. The actual site of MacKenzie's post is on the Clearwater River, about 5 miles above Lewiston, but is not visible from here. The fur trading post proved unsuccessful because the Nez Perce wanted to trade food and horses but were unwilling to engage in trapping beaver.
