August 15, 1912
A new skating pond was completed, from plans drawn up by landscape architect Loring Underwood for an earth dam behind the Chapel on Casperkill Creek. Originally referred to simply as “the artificial pond,” it became known, briefly, as Pratt Lake, after trustee Charles M. Pratt who had donated the $4,200 necessary for the project. Eventually, because the pond was bounded on the east by Sunset Hill, it became Sunset Lake.
