[Cdt-l] CDTS Columbus route KML & GPX

For some reason the recent "no trespassing" thread inspired me to break 
out the maps and reminisce on my hike (8 years gone!) As is often the 
case, one thing led to another, and (next thing I knew) I'd traced the 
route from the border to the Gila using TopoFusion software, converted 
it to Google Earth KML format, and uploaded it to the web. Compulsions, 

Here it is:


Also, in GPX format for gps units:

Maybe someone's already done this, but I haven't seen it. The trace 
shows the CDT Society route from the Mexican border near Columbus to the 
Gila National Forest at Tadpole Ridge where it intersects the "J Ley 
route" down to Silver City and on to the Mexican border. The route line 
shows the CDTS route ca. 2003 (per my guide) and is based on hand-eye 
conversions of the 100,000 scale maps contained in the guide (with 
recollections of my own), so is imperfect but hopefully useful for 
comparative purposes.

Here's the New Mexico portion of the J Ley Google Earth trace, for 


Fun trivia: It turns out the 'Columbus route' is about 20 miles longer 
than the 'J Ley route' (between the border and the point where they 
merge) - at least by the map. I believe the elevation gain is also 
significantly greater on the Columbus route (especially if climbing 
South Peak in the Floridas, which is how I mapped it).

The CDTS guide maps do a good job of showing private land boundaries, 
particularly where these maps are based on the BLM data. I can maybe see 
a few cases where the route crosses mapped private without the benefit 
of a public road, but I would think the route has been vetted 
throughout. Certainly the areas routinely mentioned on the list are 
along established public rights-of-way, and never mind the locked gates 
and signs that *seem* to indicate otherwise. (There are a few private 
inholdings in the Gila NF along Berrenda Canyon, a very common thing in 
New Mexico, and in fact these are sometimes off-limits to the public, 
including along the forest roads, so let's consider ourselves lucky and
