[pct-l] PCT Map Programs Redux

[kentr-lists at sbcglobal.net (Kent Ryhorchuk)]

For whatever reason, I have found that it is the norm for USGS maps to
be inaccurate. Most of them were drawn decades ago and roads and trails
have changed so much that you have to pay very good attention to where
you actually are. In other cases I have found them to be just plain
wrong, usually in how a trail is mapped. At least the terrain is
generally correct.

Whatever maps you want to bring on the PCT, you probably can't avoid
needing the guidebooks. This is especially true in less pristine areas
where logging or other human encroachment has changed things from the
way they were when the USGS quads were first drawn. The guidebook maps
attempt to show where the trail really is (at least when the books were
written) and also show road crossings and named features where there are
none on the original maps.

My experience was that they
were rarely wrong. Since then, folks with GPS devices have found
mistakes
but I suspect that's more due to inaccuracies in the underlying USGS
maps.
