I'd love to hear more about that trip! You should consider writing a trip report. You can submit it here on SummitPost or possibly to the American Alpine Club. I'm sure plenty of people would be willing to help you upload it.
I'm just seeing this. The logical answer is to contact the newspaper in Wyoming that did the story if they are still in existence, or contact whatever newspaper (news service?) is now in the area and see if they might have the records of old newspapers they might have acquired as the news industry consolidated. If that is not successful maybe contact a local college or university (University of Wyoming?) and see if they have any microfiche or on-line accessible records of newspapers from that era. That sounds like something of interest as you and your fellow climbers may very well be the first to have done it on New Years Day. Winter mountaineering was growing in popularity back then, especially here in California IIRC. Cheers!
