Description
This article is the first in the Alberta Lithic Reference Project series, the goal of which is to assist the identification of raw materials used for pre-contact stone tools in the province. Each article will focus on one raw material; the current article discusses a partially fused, glassy, vesicular rock that originates in Northwest Territories called Tertiary Hills Clinker (THC). THC appears in archaeological sites in northern and central Alberta. A suite of techniques indicates that it can be geochemically sourced much like obsidian. The accurate identification of THC can reveal significant relationships between occupants of Alberta and the Mackenzie Basin to the north.
