I have pieced together a map of the entire area and saved it as a .jpg file. It is big, about 7.8Mb. On 384Mb/sec DSL it is about a 4 minute download. On dial up, it is about a 25 minute download. There are two version, (1) Cathedral Range.jpg, and (2) CathedralRangeroute.jpg with a red line marking the proposed route. The route gets a little suspect in places, so your close scrutiny and input will be helpful.
Go, Think, Hike!
