I was out at a few sites where I work called Triceratops Trail, Dinosaur Ridge and the I-70 Road Cut taking some photos of trampled dinosaur trackways for our exhibits and had a pretty good day. Despite the tornadoes that ravaged north-eastern Colorado yesterday, the foothills were breezy and about 65-70 degrees with just a bit of rain.
Here's some pics that I took yesterday. Those geo and paleo fans may find them interesting. Pics of some ornithopod trackways from the South Platte Formation (Dinosaur Ridge), a small wild lizard (non-dinosaurian), a lovely look at the green/gray/maroon siltstones of the Morrison Formation, neat vertical banding in mudstones from (I believe) the Lytle Formation, and a trampled track area from the Laramie Formation (probably Triceratops and a species of hadrosaur, most likely Edmontosaurus as the formation is aged to 68 MY).

I really like the banding image. Is that iron ore?

It's iron coloration in the silty sandstone. It's beautiful! Its different layers, so I'm just assuming that it's it's layers where there was heavy amounts of saturation vs. where there wasn't a lot of water. We see that in the Morrison Fm in regards to salinated ponds/lakes in terms of the differences in color and makeup of the sand and mud stones. :)
Nifty though. A beautiful site where you can basically take a walk over 300 years and see from 90-100 my to 150 my.

300 yards. lol. Not years. It's amazing how well-articulated I can be until I sit in front of a keyboard.

Ah, OK. It's really nice looking. Of course all we have are shrubs and yucca. We do have this neat little hill that looks like a Mayan pyramid. I'll have to see if I can get a picture of it:)
