Play around. There are no links to this script, so it's not really live.

Clearly many, many areas need to be updated with the lat/long for this to work well. The admins will help update areas, but if you maintain an area, it would be great if you could add lat/long where possible.

Please give us your general feedback about this page.

That is seriously cool. Being new to climbing and all, I really like being able to locate areas before I go hiking around. As more routes get lat/long info, this will be even more useful to us n00bs.
