After several preliminary, and promising, snow reports, this is the first 
regularly sceduled snowpack report from C1, Niwot Ridge. It is very different 
from the earlier preliminary reports, unfortunately, but holding with anticipated 
(by some, anyway) El Nino type winters here on the Front Range - snowy to start 
and end, and dry in between.

We did start out with a snowy October and November, but we are still skiing on 
that snow now at the end of December. The December storms tended to be westerly, 
which is more benefitial to the west slope of Colorado than the Front Range. 
This is reflected in the basin-by-basin reports with the Upper Colorado and 
Gunnison basins having the highest snowpack (by percent of average) in the state. 
They are at 91% of average. The Upper Rio Grande has the lowest at 70%. The 
snowpack to cummulative winter precipitation ratios are about average, meaning 
there is not a climatic problem (ie. abnormally warm temperatures or other snowpack 
melting problems). This ratio is most out of kilter in the S. Platte basin, where 
snowpack is 74% of average, and the cummulative precipitation is 87%, meaning more 
snow has fallen than is in the snowpack compared to usual.

C1 conditions on December 31, 2002: 4.0 inches water equivalent in the snowpack 
(SWE) which is 71% of my 1981 to present average, and it is 16.6 inches deep. 
This matches very well with the SnoTel measurement of 3.8" and 73% respectively.

Until next month, hoping for fresher skiing conditions, and a Happy New Year!
