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?

New Moths for 2020

Like everything else in 2020, mothing wasn’t great for me in the Pikes Peak Region. I wasn’t able to distinguish additional species from the few moth photos posted to Arthropods Colorado and Wyoming, and I’m sure I missed some. But on a single trip up Bear Creek in early August I discovered two species of moths new to my database. The first (above) is probably Hellinsia homodactylus, a Pterophorid, and the second (below) is Glyphipteryx montisella, a Gelechiid, nectaring with a few tiny flower beetles.
