Landslides, eddy bars, glacial erratics, kolk ponds, anticlines, synclines, thrust faults, Ohanepecosh to Troutdale formations, lahars, tree casts, petroglyphs, and more. The central Columbia River Gorge is like a storybook of the past 40-50 million years, and we will open and read from several chapters of that book in a 10 hour bus/walking tour of a 40 mile section of the Gorge between Bonneville Dam and The Dalles.
As we turn some of those pages and take a glimpse into the incredible geology and more of the Columbia River Gorge, we will reveal many secrets that are hidden right in plain sight. This tour features huge landslides, local and distant lava outpourings that built mountains, filled lakes, and left behind the ghosts of lava-consumed forests; cataclysmic floods that reshaped the landscape; native american art saved from the backwaters of The Dalles Dam; the lush flora of the Gorge; maybe even a present-day mini-safari.
It will involve some easy walking, but more importantly, it will enlighten your mind and light your eyes with amazing and delightful discoveries.
