Thesis Preparation Investigations began with the extraction of material at natural sites. A clay deposit was identified at Chimney Bluffs State Park, located halfway between Syracuse and Buffalo, NY on Lake Ontario. This site features unique “bluffs” that are formed from eroded drumlins, or teardrop-shaped hills of glacial deposits formed during the most recent ice age. Wind, rain, snow and waves from the lake further eroded these bluffs into sharp pinnacles. These bluffs continue to erode at an average rate of one to five feet per year.
