Coast and river images from the National Map Server. Lobe outlines originally traced directly from Wicander and Monroe, 1993, but the shorline and river didn't match the USGS data, so the outlines had to be reinterpretted slightly.

Final Photoshop layers can be found here, in case updates are needed.
