This expedition plunges deep into the sculpted heart of central Washington, where ancient ice-age floods carved vast coulees, cliffs, and dry canyons that feel more otherworldly than Pacific Northwest. Traveling by rugged overland routes, the journey weaves through a very dramatic landscape.

About the event
Okay, so you are asking yourself; "What the hell is a coulee?!?"
Well, a coulee is a type of landform—basically a steep-sided channel or valley—that was carved by flowing water.
In the western U.S., especially in Washington state, coulees were formed during the last Ice Age by catastrophic floods, not gentle rivers. When massive glacial lakes burst (most famously the Missoula Floods), enormous volumes of water ripped across the landscape, scouring deep channels into solid basalt in a matter of days or weeks. When the floods ended, the water disappeared, leaving behind dry canyons—those are the coulees you see today.
Key characteristics of a coulee:
Steep basalt cliffs and terraced walls
Often dry or with only small lakes or seasonal water
