The map above shows the esker in light blue. With the exception of Dyckesville, all the towns shown are merely wide spots in the road, even the euphoniously named Frog Station. The cluster of hills around Lincoln are probably Silurian reefs. The esker wraps around the hills and breaks up into a complex system of eskers.

Above is a map of the northern and best displayed part of the esker.

	There are numerous sand pits in the esker, constantly changing due to erosion and excavation. This pit is on the north side of Dhuey Hill.
	Left and above: current cross bedding. Below: typical esker topography along County Y

	The views here are where the esker crosses Swamp Road (eastward continuation of road where County Y turns north). It wasn't simple negligence that parked a trip leader right over a deep puddle. It took carefully calculated malevolence.
	Small delta created by a recent rain
	The thin vertical spikes are plant roots encased in sand.
	Cross bedding revealed by wind erosion.

Kettle and Spodosol

	East of the esker is a small kettle.
	Left: Excavating a soil profile Below: the white layer at the base of the A horizon marks this as a spodosol. It's due to extreme reducing conditions from organic acids in the soil. The original plant cover here was conifer forest.
	Left: old road in the woods.
	Left: Kevin Fermanich has augered all the way in to the handle. This is very nearly a floating bog, although with an extremely thick soil and peat cover. The bottom is pretty mushy and finally ends in sand.
