Suffield, Alberta, is situated approximately 40km northwest of Medicine Hat, Alberta. A few "large explosive events" (100 to 500 tons) were conducted at the Defence Research Board's (DRB) Suffield Experimental Station in the 1960s. On 19 January 1961, Medicine Hat citizens felt tremors in the community as a result of five tons of TNT being detonated at the station. The station director attributed this anomaly to freak atmospheric and weather conditions. At the time the DRB was testing the effects of shock waves on military equipment.
In July 1964, the Suffield Experimental Station detonated 30,600 blocks of TNT - 500 tons - to test the largest, non-nuclear, non-confined, surface blast. Placed in various sections radiating from ground zero to test the effects of the blast were targets, dummy-men, miscellaneous instruments, mines, model ships, nose cones, repirators, vehicles, subterranean chambers, shelters, tunnels, foxholes, and trenches. Several hundred people were expected to observe the blast, including 80 "official observers" and a VIP party of military and research personnel from Canada, the United States, and Britain.

John Dickson (b. 17 Mar 1854, Scotland; d.15 April 1926, Brandon) was considered one of Brandon’s pioneer dentists. Dickson immigrated to Canada in 1857, where he lived in Hamilton, Ontario, for a number of years. Dickson then came to Manitoba and operated a grocery in Chater before he studied dentistry, graduating from the University of Minnesota in 1886. Dickson settled in Brandon where he married Anna Louise Harrison on 28 December 1891. (Source: “Pioneer Dentist of Brandon in Dr. John Dickson,” Brandon Daily Sun 16 Apr 1926)
