[pct-l] guidebook elevations

[Trekker4 at aol.com (Trekker4@aol.com)]

This topo vs newer trail placement is quite common today. The almost always  
much older topos were done from aerial photos and ground work; newer trail  
placements are usually GPS work, and more accurate; also don't forget that the  
are always relocations in many places, sometimes minor ones.
