The McAbee Fossil Beds were formed in an ancient lake bed during the Eocene Epoch, a period characterized by a much warmer global climate. The site is notable for its exceptionally well-preserved fossils, which include a wide variety of plants, insects, fish, spiders, crayfish, and even birds. This diversity makes the McAbee site one of the most significant fossil localities in British Columbia and Canada, providing invaluable insights into Eocene biodiversity and ecosystem.
