The Utah gang was back at it in the Green River Formation, which is exposed in one of the cuestas in the Sanpete Valley. It was a wonderful 100 degrees by midafternoon, and I think that even the fossil ostracodes were beginning to sweat. Our goal today was to investigate a couple of quarries, and first thing in the morning, Jesse found an very intriguing stromatolite layer about 5 feet above the top of our first quarry. There were smaller stromatolites, which provided a base for the much larger stromatolites.
We were able to look at three different quarries within the cuesta. While Elizabeth and I were working in quarry #2, Jesse went to one of the other cuestas in the Sanpete Valley for some recon work on the quality of the stromatolites there. The Black Hill quarry that Jesse visited is enormous, but he reported back that the quantity of stromatolites was disappointing. So, we hiked to quarry #3, where Elizabeth attracted yet another scorpion. (As I have learned, Elizabeth seems to have a real gift for attracting scorpions, wasps, huge bees, and fire ants.)
Quarry #3 was great!! Although we were supposed to be looking for mudcracks, our attention strayed. First, we were fascinated that the small scorpion seemed to be very angry at Elizabeth for flipping over a stromatolite (its home), and seemed to chase her. But, then things got very interesting…The scorpion rested near a small bush, and before you knew it, a lizard was stalking the scorpion. In a flash of an eye, we watched the lizard grab the scorpion and run away with the prize, all the while capturing everything with the camera. National Geographic, here I come!!
