WALLULA GAP: Bottleneck of the Ice Age Floods

When you first hear about how 15,000 years ago, glacial Lake Missoula broke free of its ice dam and raced across the Mid-Columbia Basin – some 500 cubic miles of water traveling at speeds of up to 80 miles an hour – you’re tempted to say bullshit. That’s what most scientists thought when J. Harlen Bretz first proposed his theory of a great “Spokane Flood” in the early 1920s. But 30 years later, after he and others collected more evidence, and after the advent of aerial photography made it possible to recognize giant “current ripples” in suspect landscapes, scientific opinion began its necessary shift. On a recent trip to the tri-cities, I spent time in the Horse Heaven Hills, south of Kennewick in order to see some of the evidence for ancient cataclysmic floods as laid out in Bruce Bjornstad’s guidebook, On the Trail of the Ice Age Floods. Evidently, the Horse Heaven Hills form the defining southern rim of the Mid Columbia ‘Basin’ and when the floods came, the only ...

The Road to Cloud Cap Trailhead

I was lured to the Cloud Cap Trailhead with promises of time travel back to the ice age. The information I read on the internet from the Portland Hikers field guide http://www.portlandhikersfieldguide.com/wiki/Main_Page (an excellent hiking resource!) promised spectacular views of Eliot Glacier from high atop Cooper Spur. The time travel part comes into play if one can imagine Mt. Hood’s most massive captive river-of-ice escaping its high altitude prison and joining its northern siblings in a steady southern migration. An ice age. Unfortunately, I didn’t get to see Eliot Glacier, which is why this blog entry is called only the Road to Cloud Cap Trailhead instead of Cooper Spur Hike or Eliot Moraine Hike. I’m an idiot, but don’t take my word for it. Read on and see for yourself. The instructions to the trailhead(s) were simple enough. Go to Hood River. Take highway 35 south. Follow any signs that mention Cooper Spur Ski resort, then follow Cloud Cap Road to the trailhead area. Cloud C...
