Soil moisture recorded with 43 sensors in the 4 general study locations. Most sensors were placed at 3- and 6- cm below the surface in a cardinal direction 1 m from the trunk of a tree where snow depth was also measured. A few sensors were placed at different depths for additional observations. The sensors at Duncan Peak exhibited erratic behavior 41 not observed at the other sites, with these time periods removed a limited number of observations were recorded.
