An interesting geological phenomenon east of Ogden, Utah. Photographed a week or so ago on my way home. What you’re seeing is the result of land that has been uplifted in such a way that previously horizontal terrain has been tipped about 90 degrees; horizontal layers are now vertical. The layers are of differing hardness; two hard layers sandwich a softer layer, which has been scooped out via erosion. The result is a pair of walls or tracks that form what would be just about the most uncomfortable and un-fun kids slide imaginable.
The Utah Department of Transportation put a viewing area on the opposite side of the road, allowing pretty good views of the thing. But someone also strung phone lines right in front of it, planting a utility pole right next to it. Gah.
