I've been driving through this southern Alberta area since I was child -- it's in the far southwest corner of Alberta, only minutes from BC to the west and Montana to the south. The mountain slide and the fan of boulders across the valley have always fascinated me, and as a child I would devour every book I could find on the subject.
Trapped miners, destroyed rail lines, stories of heroism, stories of amazing chance, it's an amazing historical event.
There's too much history to get into here (and trust me, I could talk your ear off for hours), so if you're interested, check out:
Frank Slide, AB -- When a Mountain Fell On A Town
Alberta Geological Survey
The mountain still "moves", is actively monitored and all those involved say it's a matter of "when" not "if" the mountain will fall again. Hi-tech monitoring means we'll hopefully know well in advance when more of the mountain is about to fall:

On the edge of the slide is the Frank Slide Interpretive Centre, our next stop on our journey...
