"Remember, you are within the Mt. Elbert Wilderness. As such, special regulations apply, including: Bicycles are prohibited..."

Seems to me, unless there is a new wilderness designation, the maps, and John Fielder's book (both admittedly older) show Mt. Elbert between the Mt. Massive wilderness and the Collegiate Peaks wilderness. Bill's online guidebook does not give the wilderness heads up at the bottom of the page as he does for others which are in wilderness areas. And the 2011 topo map does not show this as wilderness.
