By the time that Oswego deposition had been completed the eastern shore was well out of water, and the Lorraine and earlier strata of that region were undergoing folding and erosion simultane- ously. When the shore had migrated westward to the limit indi- cated by the extent of the conglomerates, a reversal of conditions 'The student must be careful here not to confound this crumpling with the later folding of the strata which has produced the Appalachians. The folding here spoken of affected only the Lorraine and earlier beds and occurred before the deposition of the Siluric and later beds. It resulted in the formation of the Green mountain chain, and is hence commonly- spoken of as the Green mountain Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original New York State Museum; New York State Museum.
