A birch leaf lies on Chatanika River ice at the collection dam for the historic Davidson Ditch, at approximately mile 68 on the Steese Highway, Alaska. An inverted siphon built for the ditch, which once brought water to the community of Fox for gold mining, may be seen at the mile 57 turnoff to the US Creek Road, the main summer entrance to the Bureau of Land Management's White Mountains National Recreation Area.
