Snow depth data for saddle snowfence, 1992 - ongoing.

A snowfence was built in 1993 on the Niwot Ridge Saddle grid to determine the effects of changes in snowpack on a number of variables. The study area was 60m x 125m. Snow depths were measured at each of 147 points within the snowfence experiment area and at 6 control locations outside of but near the snowfence experiment area. Of the 147 points, 84 were located on the leeward (east) side of the snowfence, 56 were located on the windward (west) side of the snowfence, and 7 were located along the snowfence itself. These measurements were made weekly to biweekly. Sampling locations were each given a unique point identification number so that these data could be incorporated into the Saddle GIS. The snowfence was oriented in a north/south direction and was 60 m long. Each of the point identification numbers had a coordinate within the experiment area. The first number of the coordinate was the distance in m from the snowfence in an east/west direction, negative numbers being west of the snowfence and positive numbers being east of the fence. The second number in the coordinate was the distance in m from the southern terminus of the snowfence in a northerly direction.
