2014-2015 Winter Storm Reports:
Winter Storm #2: November 14-15, 2014
Greetings from Silverton -
Sunday morning dawned clear and cold (5 F in Silverton, -4 F at Putney) here in the western San Juans following a long winter storm - our Storm #2 of the winter of 2014/2015. Storm Report (pdf)
The prior, 'tentative' Storm #1 earlier this month did, in fact, linger just long enough with snowcover over more than half of Senator Beck Basin, albeit very thin cover, to 'count' as #1 . We will find that Storm #1 layer in our snow profiles for the rest of the winter, at least at the higher elevation Senator Beck Study Plot. Now we're really in business with a half-meter of snowcover and more over the entire Basin.
A special thanks to the many of you who have made your Winter 2014/2015 Friends of the CSAS contribution ... kudos to you!

Winter Storm #1: November 2-3, 2014
After a dry October, with only a couple of very minor and short-lived snowfalls that quickly melted back to the ground, we finally received a snowfall last weekend that may comprise the basal snowcover in Senator Beck Basin for this winter. We'll see - we're in for a sunny period ahead and we may lose this snowcover too. But, so far, the new snow is hanging in there over the majority of Senator Beck Basin and at our two study plots. So, tentatively, I'll consider this event as Storm #1 at Senator Beck Basin for winter 2014/2015. Storm Report (pdf)
