The Winter 2010 issue of Trail & Timberline (http://www.cmc.org/Upload/ArticlesDirectory/22.pdf) has the following in a "Happy Birthday" message to Virginia Nolan on page 13:
"First woman (and 3rd person) to reach the summits of all 69 peaks above 14,000 feet in the lower 48 states. (Guinness Book of World Records Holder)"
I'm curious which peaks are included in her list of 69. I've contacted CMC in order to learn more. I also see no listing of any US mountaineering accomplishments in my 1999 edition of the Guinness Book of World Records. Thanks for the information.
