A large irregular chunk of naturally occuring ‘native’ copper. Source Bern Will Brown found this sample at an old cabin site on the Dease Arm, Great Bear Lake. Copper prospectors were active in the Great Bear Lake area during the 1920s-1930s which could explain why this mineral sample was found there.
An ancient horse jaw from a mud flow of a collapsed slope near Midway Lake, on the Peel Plateau, in the Fort McPherson area. It was recovered by Bernard Lauriol of the University of Ottawa in 2010. North American horses died out 12,000 years ago but not before they migrated to Eurasia.
A stromatolite fossil specimen with a concentric circle pattern, collected in 2001 by Dave Smith at Utsingi Point on the East Arm, Great Slave Lake. Stromatolites are the oldest record of life on Earth, dating to billions of years ago. They are formed by colonies of blue-green algae or cyanobacteria excreting lime and trapping it in microbial mats. Commonly in the shape of mounds, they may also form in columns or sheets.
