With an ascent of Mt Zwischen on 9/21, Bob Packard has climbed the top 100 prominent peaks in CO. Not bad for an AZ resident.
To me this is one of the more interesting CO peak sets, with summits from all over the mountainous part of the state, and at all elevations.
Looks like Mike Garratt finished this list on Pinon Mesa earlier this year. I believe Bob Martin had completed the list with substitutions years ago.
