RE: Utah Rocks! - Episode 1: Goblins and Jasper Geodes
absolutely love the geology and history packed into this post. it's interesting to see how the climate and soil changed, somehow dramatically. i would think that the color change would be a gradual shift rather than a hard line. fascinating to consider and incredible photos! so happy you are enjoying your new home :)
Yeah the boundary between the red Entrada Sandstone and grey/green Curtis Formation limestone in particular is really sharply defined. It makes sense because that boundary is from when the area that used to be a beach / on the edge of the sea was totally unundated by the sea in a geologic instant :) We are loving Utah so far! I actually plan a couple more posts about this trip, I took a ton of photos and also video clips of the drive through the mountains which was also cool.
excellent! looking forward to it. always had a fondness for utah redrocks since i did summer camp there when i was a teen :)
