Most of the bedrock removed during the digging of the Erie Canal was primarily limestone and shale. These materials were prevalent in the regions through which the canal was excavated, particularly in areas like the Niagara Escarpment. The removal of this bedrock was necessary to create a navigable waterway that connected the Hudson River to Lake Erie, facilitating trade and transportation. The excavation was a significant engineering challenge, requiring innovative techniques and considerable labor.
