WINTER SNOWFALL AMOUNTS
Winter 2011 – 2012 (Total: 81.50″)
Winter 2010-2011 (Total: 75.75″) – most of it came in dribs and drabs throughout the winter. While much of the rest of Colorado north of us received record snowfall, we could only see the teasings of it. So often the clouds hung on the edge of South Park, but refused to make it over a few more miles to us.
Winter 2007-2008 (Total: 132″)






I can see them in the attic of my mind!
