3/17/2010 7:00 AM 0.00 0.0 M 22.0 M Yesterday the drive to Tennessee Pass was especially beautiful! The snowcovered peaks stood out against the brilliant Colorado blue sky! By last year at this time we had had numerous dust storms which left "brown peaks" and speeded up melting. Maybe no dust storms and our cold temps are the reason our skiing is amazing despite lower than average snowfall. Let's hope we don't have any dust storms this spring!
3/18/2010 7:00 AM 0.00 0.0 M 22.0 M I will have to figure an average in the yard since some spots are bare and others have more snow. The past 2 or 3 days have been warm and a lot has melted in the valley.

4/6/2010 7:00 AM 0.78 6.5 0.68 24.0 M The snow began yesterday evening and when it started it was very wet snow which melted on contact. This would explain the difference between the tube and the board. The amounts on the ground will vary from 6.5" where the snow was melted up to the 24" which is on the north side of the house. It is not snowing currently. There is a lot of dirt in this snow.
4/7/2010 7:00 AM 0.59 10.5 0.67 34.0 M The ski area received 13" yesterday and 19" by this morning at 5:30, a total of 32" by 5:30 am in 48 hours! It is snowing very lightly. It took a while to melt the samples.

4/12/2010 7:00 AM 0.00 0.0 M 11.0 M Sunday was a spring day! Much of the valley snow on the south facing side melted. About 75% of the ground is showing and the patches remaining are in shaded areas.
4/13/2010 7:00 AM 0.09 M M M M We had rain for the first time last night. The forecast was for snow so I did not use the funnel and inner tube. Isolated patches of snow are remaining on the ground at this elevation and on this side of the valley.

4/26/2010 7:00 AM 0.12 0.3 0.02 M M There were snow flurries yesterday morning with no accumulation. The precip yesterday evening began as rain which is the reason for the difference between the site and the tube. I did not have the funnel in place thinking the rain would turn to snow so there may have been even more moisture out of the this storm.
