I almost ran over this little guy in southeastern Colorado last week. I couldn’t see a rattle and thought he was just a bull snake but he had a heart shaped head and he buzzed that tail as fast as he could. He just didn’t have rattles yet.
In another area, I looked over a cliff...not something that I’m really in the habit of doing and noticed a limestone layer exposed by Carrizo Creek. It had kind of an odd pattern on it.
Sure enough, those are dinosaur tracks. At least 2 individuals, probably sauropods of some kind.
I went down to the tracks and on the way back up noticed this
Rocks don’t pile themselves. In the area, some sheep herders make pens out of piled up rocks but this wall didn’t enclose anything. It’s part of a game trap with a jump at the end. It’s likely for big horn sheep. I’ve seen these walls in a couple of other places in Colorado.
And, since this is a bike forum, here’s a gratuitous bike picture. 1998 Moots YBBeat against a water tank built in 1940 (signed on the side)
