Figure 7. Photos of apparent varve sediments retrieved in the Orient Point 

 boring drilled into the Orient Point buried channel. These suggest 

 a major glacial lake occupied the Long Island and Block Island 

 Sounds during Pleistocene time. Each pair of light dark lines 

 represents a summer and winter episode of lacustrine deposition 

 (from Woodward-Clyde-Sherard and Associates, 1965).
