Last Thursday, Karen Blumer, Vicki Bustamante, and I went north to Albany. After leaving Long Island it was bedrock all the way north along the Hudson River. The advance of the last ice sheet of the Wisconsin glaciation purportedly carved out the river basin that is over a mile wide in some places and stretches a good 200 miles. It is oriented north to south, so it makes sense that a quarter-mile-high glacier coming from Canada would be capable of making such a deep gouge and simultaneously creating the Palisades along the west side.
You hardly hear anyone call it Lake Munchogue these days. The Hagstrom Suffolk County Atlas still has it down by its Native-American name, while including Oyster Pond in parentheses below. Many of the other water bodies on the South Fork retained names derived from the local dialects of the Algonkian language since settlement. There are Shinnecock, Noyac, and Mecox Bays as well as Lake Agawam, Poxabogue, Wickatuck, and Sagaponack Ponds and Sebonac Creek in Southampton Town. While in East Hampton there are Accabonac and Napeague Harbors and Napeague Bay.
