12/16/2010 7:30 AM 0.00 0.0 M M M Drifts are frozen over extremely hard now. The only way to clean them up around work areas is to scoop them one bucket at a time with the bucket loader.You just cant push them around. Also, we cant get to where we cut Christmas trees up in the Crazies. Drifts are too high. That would be at approximately 5700 feet in elevation.

12/30/2010 7:30 AM 0.21 1.2 M 2.0 M Temp is 7 above. Wind has stopped and very calm.It looks as if it is snowing all around me.Its the old "Wormser Hole" effect that we have here. Friends tell me it snowed much more in town but the snow map doesnt seem to agree with that. When the wind picks up drifting will be an issue but not much of one with this little snow.
