North Grenville Historical Society Presents:
Black Ice Rock: Obsidian and Human Movement into the Ice-Free Corridor

Date: March 12th, 2025
During the last Ice Age, a single sheet of ice stretched from the Rocky Mountains to North Grenville and beyond, while another lay draped over the mountains to the Pacific coast. As the ice began to melt more than 15,000 years ago, some of the first inhabitable land in the interior of what is now Canada began to appear, and plants, animals, and humans began to move into what is commonly known as the “ice-free corridor.” In a public talk to the North Grenville Historical Society (12 March 2025), Canadian Museum of History archaeologist Dr. Gabriel Yanicki will be speaking about how recent analysis of some of the oldest obsidian artifacts in western Canada is reshaping understandings of the earliest peopling of this region, long thought to be the first route of human entry into the Americas.

Talk begins at 7:00 pm (doors open at 6:30 pm).  Free admission.  Refreshments.
