Data from Coast and Geodetic Survey. into the continental sheif. Even in the Hudson valley above New York City, the narrow inner rock channel has a depth of hundreds of feet (see plate 38) and is mostly submerged below tide water. Without any question this submerged Hudson channel was cut when the region was dry land, and thus we have positive proof that late in the Tertiary, and possibly extending into the early Quaternary, the region of southeastern New York was notabl) higher than it is today. Conservative estimates place the amount.
