CALGARY, CANADA—According to a report by Newstalk 770, a hand-stamped brick, metal pickax heads, rail spikes, and window glass that could date to the construction of the Canadian Pacific railway in the 1880s were uncovered by utility workers in downtown Calgary. The artifacts were found along the old railway line in what is now a power substation. Archaeologists have been called in to try to determine the exact age of the tools.
