Sentinels at Frank Slide.


On our recent trip to the Crowsnest Pass, my hubby and I spent a couple of hours walking among the massive ruins of the peak of Turtle Mountain, which slid over the east side of the town of Frank at 4:10 in the morning on April 29, 1903.  The slide lasted just over a minute and a half, and at least seventy people were killed, buried under 82 million tonnes (90 million tons) of limestone.

It is an overwhelmingly surreal experience to spend time in the slide zone and try to comprehend the enormity and horror of it:  an entire mountainside collapsed and spread over three square kilometres.  It is now widely accepted that the mountain was geologically unstable and unseasonably warm weather as well as mining activity at the base of the mountain may have contributed to the slide; while no mining has taken place there since 1917, Turtle Mountain remains on “slide alert” and is monitored by the Alberta Geological Survey via radar and laser mapping systems.  (You can watch a short video about some of the technology being used here).


The fall colours weren’t as rich as they must be now, three weeks later, but the trees were still incredibly beautiful.

After I published this post yesterday, my Grandpa sent me a photograph that he took a few years ago as he flew over the slide zone in his sailplane.  It is an incredible perspective of the magnitude of the disaster.  (Photo credit – W. Mueller)

    • We were fortunate to find a side road that took us even closer to the base of the mountain than the area the photos show. You can hike right to the mountain and I believe it is commonly climbed (I’m not sure which face, however). We’re thinking of doing the hike maybe next year. But I wouldn’t ever climb it, that’s for sure!

  1. What a story, scary and fascinating at the same time! The photo’s are beautiful. Thanks for all the links too, the legends and folklore after the disaster are amazing. Have a great weekend!

    • I hope your weekend has been wonderful!

      The stories are really fascinating, aren’t they? There is an excellent interpretive centre on the site that offers a ton of information about the slide and the history of the region; it is really interesting to tour.

  2. This is fascinating and terrifying at the same time! The pictures you took are terrific–the bright trees against the gray, dead-looking rocks–so striking!

  3. Wow, your photos really capture the power of this place, I am definitely going to check out the links, thanks, Annie

    • I think I read in the Wikipedia article that you could hear the rocks falling as far away as Cochrane, which is located just northwest of where I live in Calgary. We are about 200 kilometres away from the slide zone. Insane!

    • It is the second largest rock slide in Canadian history (the biggest occurred in Hope, B.C. in 1965) and the deadliest. It is incredible to think that just a few kilometres from where this slide took place, a mining disaster at the Hillcrest Mine killed 189 men in 1914 – the worst mining disaster in Canada. A place beset by tragedy.

I'm delighted to hear from you - thanks so much for your comments!
