The Columbia River serves as the central artery of this landscape, marking the interstate border between Washington and Oregon. Much of the river’s width here is occupied by Lake Wallula, the reservoir created by downstream damming, which surrounds Van Skinner Island and creates a broad, watery divide between the Columbia Plateau in Washington and the dry canyonlands of Oregon. This survey captures a terrain defined by deep erosional cuts, where the high benchlands are punctuated by dramatic features such as Juniper Canyon and Spaw Canyon.
