The Frank Slide

At 4:10am on April 29, 1903, Turtle Mountain shed 110 million tonnes of limestone, covering three square kilometres of the valley floor, and demolishing part of the town of Frank. Most of the estimated 100 individuals in the path of the slide were killed.

Two railway brakemen set out across the rocks to stop the early morning train. Only Sid Choquette made it across. Talk about beating the cutoff! He choked on dust and dodged unstable debris in order to warn the train, thereby averting further disaster, and his name lives on as the first person to navigate the terrifying landscape. Sid was given a reward of $25 and a certificate of commendation from the railway.

Even now, locals still debate what caused the slide, but one thing is for sure – we know the mountain will fall again. The rocks still entomb part of the original village of Frank, and subtle reminders, like the old mine entrance, poke out here and there. Solemn reminders of the fierce power of the mountains.

The community continues to thrive and embrace its history. The Frank Slide Interpretive Centre is a premier attraction in Crowsnest Pass, and a cornerstone of our local heritage. No visit to is complete without stopping in.
