Subject matter of the images seems to be mostly from the Thompson Okanagan region, though most do not have any confirming identification. Images include Kamloops and other unidentified towns; Boundary Museum; Kettle Valley Railroad; a dam; bridges; a mining museum; nature scenes; the Dewdney Trail; and a “Canadian North Pacific’s Last Spike” historical marker in the Nicola Valley.
