[Various (1971)] Most features could not be excavated during the 1967 field session and it was only in the Fall of 1968 that the water level dropped sufficiently to allow excavation of the features. PHYSIOGRAPHY AND GEOLOGY OF THE ALLEGHENY PLATEAU The site lies along the flood plain of the Allegheny River in Cattaragus County, New York, in the southernmost area of New York State in the Unglaciated Allegheny Plateau. The Allegheny Plateau is a highland area cut by various valleys, the site lying in one of these. The hills surrounding the site rise to an elevation of 22002300 feet. The sides rise very quickly from the valley floor which is only a mile at its widest point. The river flows in a northeast/southwest direction at this point between Red House and Cold Spring, New York. The river has changed position from 1923 to 1961, as seen in the United States Geological Survey Maps. Thus, it is entirely possible that it flowed much closer to the site which is now 350 ft, from the bank. The depression noted on the map (Plate 1) would appear to be the remnants of the old river channel or oxbow. The bedrock in this region is composed of sandstone and shale and the soil texture is medium to fine particles. The site rests on a sterile sand and clay subsoil. It is covered by 1 to 2 ft. of overburden which is the Middlebury silt loam series or Wheeland, from a lower and less well-drained terrace.
