Nearly 15,000 years ago, where Montana and Idaho meet, a massive ice dam at the end of colossal Lake Missoula collapsed. In a series of repeated floods, the lake emptied, sending surges of water across future eastern Washington state.

Each flood had a water flow 10 times that of all the rivers in the world combined. Walls of water nearly 800 ft high carved massive coolies and drilled potholes into the basaltt. It carried giant boulders hundreds of miles.

The remaining landscape is called the Scablands.

The idea for this tour started on a quiet paddle on the Palouse River. Canyon walls were glowing. Everything was still. And one of us said, "How could we experience the ice age floods?" 

Not a quick overlook, not a day trip, the full path.

That one little spark then turned into an email.

That email turned into a list.

And then before we knew it, we had a spreadsheet that was starting to shape up into a full-blown expedition.

Flood outburst origins, coolies carved in minutes, spillways miles wide, dry falls the size of cities.

So here's the route. Here's the plan. And here's where you're coming with us.
