What caused Dry Falls?

Another solid NOVA effort exploring the science behind the puzzling 400-foot high, 3.5-mile Dry Falls in central Washington and how it came to be. It takes a while to suss out the full story, as the video takes its time with historical reenactments, contemporary interviews, and some of the sensationalized video production we've come to expect when revealing "secrets" and "mysteries" on film - spooky video effects and dramatic music leading up to the mind-blowing truth Soon To Be Revealed! And that mind-blowing truth - that all this peculiar geology was caused by the catastrophic collapse of an enormous ice-dam holding back the waters of the once-massive Glacier Lake Missoula 1,000 miles away - is just mind-blowing enough you'll happily sit through the animated sequence depicting the collapse of the damn several times.
