Did you know Oregon used to be at the bottom of the Pacific ocean? At least, most of it was. You can see the 26-million-year-old limestone that made up the ocean floor in the bottom left corner of this photo! The limestone erodes faster than it's 15-million-year-old volcanic basalt "topping", creating a pathway behind the waterfall you can walk through as you explore it's amphitheatre-like cliffs! We got absolutely soaked but it was a rush being underneath a falling river! The same event that covered this limestone was so widespread that it completely rerouted the ancient Columbia River into its current path. It was fast too. Covering a distance of 310 miles from its source in about a week. Eventually 63,000 square miles of fresh basalt had been laid down in the PNW, and has been named the Columbia River Basalt Group. It covers all of the Southeast quadrant of Washington, into Idaho, and through all of Northern Oregon to the coast. This basalt is clearly exposed in places like the Columbia River Gorge, stripped by the Lake Missoula floods I mentioned in prev posts!
The eruption emptied out so much material that its massive and now emptied chamber collapsed, creating a "heart-shaped" plain extending from Maupin/The Dalles in Oregon all the way up to Spokane in Washington. This plain is now called the Columbia Plateau or Columbia Basin.
I spent the day last weekend exploring a popular natural attraction I'd had yet to explore until now! It was such a nice relaxing day with my partner @julia.kittystyle and our good friend @gabzilla96. I hope to come back here when the snow turns to flowers!
This is Silver Falls State Park. While it's the biggest state park in Oregon, you can still hike around the whole thing in an afternoon and a leisurely pace. Check it off your list this spring! And don't forget to check out their historic lodge/cafe!
