Summary

In April of 1903, Turtle Mountain fell. Long known by indigenous nations to be dangerous, the town of Frank built at its base and mined into its sides nonetheless. In the early morning hours of April 29th, 100 million tons of rock broke free and hurdled down the mountain, killing 70 people and burying much of the town in nearly 100 feet of debris. It was over in less than 90 seconds, but has remained Canada’s deadliest rockslide.

sparkling glacial blue lakes. Walls of rock looming dramatically over the highway are some of the

most photograph peaks in all of North America. The ice line parkway, the route that winds about

140 miles through the heart of it all, is often crowned the world's most scenic.

And an entire outdoor community, economy, and culture has sprung up out of the belief

Not just the Rockies, but mountains anywhere.

Online or outside, you're bombarded by Gortex fashion,

trail running shoes, summit selfies, freeze-dried food, climbing guides, gondola rides,

Naljean pride, all trails review, ultra-light gear, and summit beers, all seemingly poking and

prodding and promising that you could be no happier in life than you would be at the top of a mountain.

And maybe they're right.
