Oregon is full of volcanic landscapes from different periods in Earth’s history. The Mascall Overlook near John Day, OR, is stunning.
15 million years ago, this was a receding forest being replaced by grasslands. It was populated by horses, camels, and giraffe-deer. Then, as so often happens in Oregon history, a volcano exploded. The upheaval filled the valley with lava and ash and pushed up the plains, creating this unique landscape and capturing the denizens in fossils who weren’t fortunate enough to escape .
Glad we ran across this gem in our wanderings about the state.
