Unexploded mortars possibly from WWI discovered at Pearson Field in Vancouver

Unexploded mortars, potentially dating back to World War I, were found during construction at Pearson Field in Vancouver, prompting a response from local authorities. An archeologist discovered the first device, leading to the involvement of the Vancouver Police Department's Mobile Explosive Device Unit and U. S. Air Force personnel, who safely detonated the mortars. These devices are identified as Stokes mortars, which were widely used during the war.

Pearson Field, operational since 1905, has historical relevance as it served as a site for military aircraft component production during WWI. The ongoing construction project aims to enhance the airport's electrical systems, with funding from state and federal grants. This incident underscores the potential dangers that can arise from historical military ordnance found in modern construction sites. Additionally, the lack of information on how these mortars ended up at the airfield raises questions about the site's past usage. Overall, this discovery serves as a reminder of the intersection between history and contemporary development.
