Something to keep in mind is that some of the free download map data can be
pretty old. For example, the Mt. Adams West (WA) quad has a 1970 date. On
this map, the location of the PCT is different compared to the 1998 map
data found in the National Geographic TOPO! map of the same area. The PCT
guide book seems to reflect the 1998 map data.
The free maps are probably OK for basic reference, though.
I put together a graphic that shows the difference between the 2 sets of data.
Hope this helps...
