Climate data for the study site: (a) cumulative monthly precipitation and 30-yr mean from Cedar, MN (Minnesota Climatology Group, 1998), and (b) soil temperature at 50 cm for the monitoring stations (PS = peatland; TS = toeslope; BSL = lower backslope; SS = shoulder).

View larger version (41K): [in a new window]   Fig. 4. (a) Average, minimum, and maximum locations of the well observations for the study period and the zone of redoximorphic features. The shoulder station does not have a mean or minimum because the water level was frequently below the 300 cm, the deepest extent of the well. The vertical relief is exaggerated to show the trends in the water table. (b) Well observations for the study period (corrected for elevation: z = 0 at the edge of the peatland).

Values are reported with respect to the elevation of the peatland (dashed line). The shoulder station is not included because water levels were frequently below the depth of the observation well.
