The San Juan River is a tributary of the Colorado River. jf
The Gooseneck of the San Juan is near Mexican Hat, Utah. It has been photographed by a great many professional photographers and millions of amateurs. You might look in the PHOTOFORUM and see if their is a GIF available online. Another place to look would be in the books of…
My personal favorite for a basic Earth Science book is _The Field Guide to Geology_ by David Lambert (ISBN 0-8160-2032-9). It is well illustrated, and the writing, while not in great depth, is clear and lets you begin looking for more detailed answers to questions. If your not familiar with…
I dunno may be we should retitle the thread movieland geology. Have you ever been to Monument Valley on the Navajo lands near Kayenta, AZ? John Ford shot many westerns there. It is awe inspiring what a little water and a lot of time can do. My wife and I…
"…I recognize it in the start of the "Arena" episode of Star Trek." Yes, but are the rocks really made out of papre maiche(sp?)? My wife and I are going hiking in southern UT over spring break. If you're flying over, have the pilot dip the wings and we'll wave.…
"…including a couple of Star Trek (the Kirk/Spock generation) episodes." That description fits about 99% of southern UT. If the ridge looked like giant flatirons or Stegasaurus plates were leaning up against it, I'm more inclined to think it was the San Rafael Swell or Comb Ridge. jf
"I saw a fairly flat part of the Colorado plateau with a narrow nearly-linear feature of great length prominent – it involved sharply uptilted rock layers and did not seem to be any sort of river-generated feature." The Waterpocket Fold, San Rafael Swell, and Comb Ridge are all in the…
Oops. I think I forgot erosion is an ongoing process. Thanks for straightening me out. "…but those guys didn't show up for the frist two years…." Sort of like how the scissors are always in the last place you look for them. jf
#Out of sequence fossils
Message #142326
"Do fossils from one time period ever appear preserved in sediment of a later time period as the rock in which they were originally present erodes or dissolves and is redeposited as sediment? Or is the erosion process so complete that this doesn't happen." I should answer that question the…
"The average particles in a given layer are consistent within the layer. Each layer is world wide." Neither of these 2 statements is true. There are many layers of water formed sandstones and shales that have very different particle sizes. The differences are accounted for by differential rates of erosion…
"The sandstones and clays are layers of very consistent size particles stretching over very large areas. They are composed of very fine smooth round particles , unlike the products of erosion." The particles forming the various sandstones of the GC are not all constent in size. The smoother and rounder…
