After Wichita, I went to Boulder, to visit a friend I hadn’t seen since The Dark Ages, spend a lot of time outdoors, then head out again to an industry-related trade show. Colorado was a stunning contrast to Kansas: it was hilly, people were fit, and no one smoked indoors.

I am pretty bad at “seeing” geological things, but the printed guide was exceptional at explaining what I was looking at. The pictures also matched!
With even enough detail that I could walk up to a specific rock of interest:
There was enough detail that I could walk up to a very specific rock of interest, like this Forelle dolostone block at Stop #13!
Near the end of the route (this was an out-and-back) were two impressive blocks of the Fountain Arkose that tumbled down the side of the mountain. This one is resting on its side, which is why the bedding is vertical.
Geology is awesome!
Between stops #2 and #3, I saw a large set of prairie dog mounds:
The critters were all over the place. Whenever the trail would lead me to a spot relatively close to the mound, one would lay across the top of the hole, keeping an eye on me. Occasionally, it’d chatter to other prairie dogs around the area, probably making editorial comments on my being a tourist. Occasionally, I’d come across a sign telling dog owners to not let their pets chase prairie dogs. (Curiously, I later saw a mini-dog try to take on a small herd of disinterested cows.)
The trail is called “Old Kiln” because there is… an old kiln:

This was believed to have been constructed in the 1880s and not a very efficient design. (There’s much more richer text by Dr. Hirschfield.)
Stop #10 had this interesting cross-bedded sandstone in the Morrison Formation.
The culmination of the out-and-back tour was being able to see this exposed fault. From here, the return trek is forward through time, with improved perspective.
In this “knob,” there are two formations, Fox Hills (light, older) and Laramie (brown). The Fox Hills block is a horst.
This area was very popular with mountain bikers, and for good reason.
