Kettle Point Chert (SW Ontario)
Kettle Point Chert also Port Franks Chert ( SW Ontario )
Kettle point chert is from Kettle point on lake Huron in SW Ontario.
Blue to grey to brown to black in color.Waxy luster with a dense non-porous texture, fair to good knappability.
A rare outcrop of an Upper Devonian shale called the Kettle Point Formation. Just off shore, below the Kettle Point formation, is a layer of the Hamilton Group of shales and limestones which contains a large amount of light-coloured, high-quality chert. When lake levels were lower, during the retreat of the Wisconsinan ice sheets, the chert was exposed and could be mined. This made the region a site of human occupation for at least 10,000 years. Kettle Point chert was dispersed to the far reaches of the region as projectile points, scrapers, and other tools.
Outside the Ontario region most Kettle point chert is seen almost exclusively in late paleo-indian Hi Lo and Holcombe fluted points" A quote from Prehistoric Chert types of the Midwest by Tony DeRegnaucourt. First photo is two pictured Hi Los I acquired Ex: T. DeRegnaucourt.
