Friday fold: Nice gneiss from Salt Lake, Utah

Posted by Callan Bentley

Another guest Friday fold… this one from my colleague Tiffany Rivera of Westminster College in Salt Lake City, Utah, the one who brought you yesterday’s thrombolite pictures

Tiffany writes that these shots come from

a man-made boulder field / berm along the lake. The boulders were these beautifully folded gneisses. Antelope Island exposes some of the oldest rocks in the Salt Lake valley, but I don’t know the geology out there very well. I’d assume that the boulders were harvested on the island.


Here’s the good stuff:



Lovely! Thanks for sharing, Tiffany.

Happy Friday, everyone. I hope to see a lot of you next week at the fall meeting!
