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).
