well, there are the Kootenai Falls and the swinging bridge outside of Libby Montana...and there is therberkely pit in Butte, MT....its a mining pit...

then there is the lake pend o'reille....there is a fabulous historical cruise (that operates out of Hope, ID)that talks about the creation of the valleys...from Missoula to the pacific ocean....there was a lake where missoula is (and a very large portion of montana as well)...that was held off by an ice dam over 2,000 feet high...now when that ice dam was breached....a 2000 foot wall of water came crashing down running it's way to the ocean, carving out landmarks like the Columbia River Gorge....it had a backflow of 100 miles....but then it did not happen once....but they say at least fifteen times....

but anywas...nice song..
