The Lake Catherine Quarry is a prehistoric stone quarry in Hot Spring County, Arkansas. The site was used as a source of black novaculite, a relatively rare form of chert. Evidence of Native American quarrying activity at the site includes quarry pits, spoil piles, and a scattered talus slope of rejected materials. The site is untainted by historic quarrying, providing a potentially significant window into prehistoric quarrying methods.〔(【引用サイトリンク】title=Summary description of Lake Catherine Quarry Site )〕 The quarry site was listed on the National Register of Historic Places in 1975.〔 ==See also==
