Hiking the Rippled Niabrara Sandstones

Hiking the extensive trail system that connects Red Rocks Park with Section 16, west of Colorado Springs, one encounters an impressive array of ripple-marked sandstones, a beach back in the Mesozoic, now dipping at almost 90°. The so-called “White Acres Trail” should have been named “Ripple Mark Trail.” The steep east-facing slope of the hogback seems to be Niabrara sandstone, but is backed on the west by Dakota SS, both of which form hogbacks. But how about these classic ripple marks?
