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.
A chart rolling device, containing a scrollable navigation map of the Mackenzie River, used on the Canadian Coast Guard Ship Tembah. The Tembah was in operation from 1972 to 2010. During the summer of 1989, the ship patrolled the Mackenzie River from Mile 778 to the River Delta.
A moose call made from a juvenile bull moose scapula (shoulder bone). A hunter uses it by scraping it up along a tree during the rut season to create an attractive sound. The object has been carved to easily fit a hunter’s hand.
A 1957 Land Rover vehicle, owned by land surveyor and mining engineer John Anderson-Thomson. Among his many accomplishments, Anderson-Thomson was responsible for surveying an all-weather road linking Hay River with Yellowknife. This Land Rover was the first private vehicle to drive up this road when it was still under construction in the spring of 1959. The stretch of road was a mere right-of-way clearing through the winter bush. John Anderson-Thomson and his wife Janet completed the trip from Fort Providence to Yellowknife in five days under strenous conditions and with considerable damage to the vehicle.
These bird eggs are a small sample of 517 eggs collected by Yellowknife geologist and naturalist William McDonald. Most of the eggs were collected between 1940 and 1955 in the Great Slave Lake area, a prime habitat for waterfowl, raptors, and other migrating birds. The pigment on an egg helps to camouflage from predators while in an open nest, and also protects from ultraviolet radiation. The collection is significant because it is well documented with excellent notes on when and where the eggs were found, and the great variety allows for comparison within a range or species. The age of the collection is of interest as well: the eggs were collected before pesticides were widely used, which caused shell thinness and fragility during incubation.
