The Snake River carves a deep boundary between Oregon and Idaho, defining the eastern edge of this 2020 survey. High above the river corridor, the landscape is dominated by expansive plateaus and ridges including Lord Flat and Mormon Flat, which provide a sense of the high-elevation grazing and landing grounds in this part of the Nez Perce National Forest. The presence of the Lord Flat Airport on a remote ridge underscores the isolation of the terrain, where access is often limited to forest roads like Cow Camp and Old Somers Creek A.
