I thought the same, but you can't add routes to Areas & Ranges. The ice routes are commonly referred to as in Hyalite Canyon rather than the actual mountain they're on, so I figured this would be the easiest way to put the info on SP
Great info, but would be much better onan Area/Range page. You can add routes to it by clicking on the 'create page' option, and then adding your new route to this page with the 'attach/detach' option.
