The surficial geology consists of glacial and alluvial deposits. The exposed sediments are primarily glacial till and alluvium although lacustrine clay has been observed in the banks and the bed. The bedrock consists of red beds including shales and mudstones as well as grey sandstones and grey shales.
Superficial deposits (or surficial deposits [1]) refer to geological deposits typically of Quaternary age (less than 2.6 million years old) for the Earth. These geologically recent unconsolidated sediments may include stream channel and floodplain deposits, beach sands, talus gravels and glacial drift and moraine .
Beneath the surficial deposits are lake-bottom silt and clay, which overlie till and shale bedrock. [9] A small rill caused by the lake's drainage created Patroon Creek, Sand Creek, Lisha Kill, Shaker Creek, Delphus Kill and the Salt Kill in the town of Colonie, New York. [11]
