In the map in the pdf - is the left edge of the purple
area supposed to be the ridge? If it is it goes
straight north. But the USGS ridge line and supposed
county border slants northeast; it most closely mimics
the purple county boundary in the pdf map. I think if
the TP marker were on the pdf it would still fall east
of the purple line.
