Just west of the intersection of State Hughway 64 with US 141 a gravel pit provides a cross-section of the esker. The photos below were taken in this pit. A bit further west on Highway 64, the esker parallels the road as a prominent ridge. Walking into the Pound Esker. The entire access road was once occupied by a gravel ridge that has been dug away.
Most students estimate the slope as being much steeper than it really is.
The pit was dug mostly to get gravel for concrete, and the sand was left behind. It's a popular place for dirt bikers. Students usually estimate the steep face of the pit as having a slope of 45 to 70 degrees, but this photo shows that slopes in unconsolidated materials are actually pretty moderate, typically about 30 degrees. A view from the top of the esker, looking back at the excavated area. In 1997, a sharp-eyed student spotted a buried bone in the embankment along the southwest side of the pit.
