June 19, 1914
An explosion in the Hillcrest mine in the Crowsnest Pass region of western Canada kills 189 miners. It devastated the town of Hillcrest, which had a total population of about 1,000, leaving 130 women widowed and about 400 children fatherless. Many of the miners were buried in a mass grave in the Hillcrest Cemetery. It was the worst coal mining disaster in Canadian history.
