Taking a week long GIS/GPS course through CCC here in Auburn. Amazing how powerful the technology can be to us trail/waterfall junkies in making really accurate and amazing maps. This was done in about 5 minutes through ARCGIS:
Since I'm going to be teaching this as part of my curriculum, I am thinking that having my students make maps complete with trail designations, lengths, scales, and titles would be good for a few of the local parts, and then exclusively have them available from NYFalls.com - with us providing them to the smaller parks with maybe a blurb about the site.
Also - a great website is http://www.everytrail.com
for downloading garmin data right to google earth or the national topo filles
