Frank's Slide

Here in Alberta, not too far from Lethbridge in the Crowsnest Pass there is a place called "Frank's Slide". It used to be a mining community back in the late 1800's, but thanks to an avalanche is no more.

On April 29, 1903 in the wee hours of the morning 90 million tons of limestone fell from Turtle Mountain in just 90 seconds onto the unsuspecting, sleeping town of Frank. It was primarily caused by fault lines in Turtle mountains teamed with coal mining inside the mountain and a quick freeze the night before.

Of the 600 residents of Frank 70 were killed, into the 1920's houses were still being unearthed, the entire town was not destroyed, but many fearing a similar incident moved on to New Frank, which is the present town of Frank, AB. In 1911 a Royal Commission study found the North Peak of Turtle Mountain to be structurally unstable and any remaining residents of the original Frank moved on.
