Western Cascades, Southern Oregon, Possible Faults, Slope, Geology, Aerial Photo On 1-meter DEM

Topographic discontinuities suggest possible Neogene-Quaternary normal faults in the Western Cascades of southern, Oregon. 3D slope, geologic maps and aerial imagery draped on 1-m DEM. Faults are black lines. Darker is steeper slope. Black patches in the DEM are no data.
