The best preserved terraces of the Upper Lake Newman were 

 found in the neighborhood of John Brown's grave just over the 

 northwest edge of the sheet, along the West branch of the Ausable. 

 The name of the lake is derived from the town of Newman, the 

 terminus of the Delaware and Hudson Railroad, where well-pre- 

 served levels occur.
