Grand Canyon Day 1
This past weekend my Geology 111 class went on a field trip to the Grand Canyon National park. We are at school in Rexburg, ID that's 14 hours away! We were gone for 3 days, so naturally I have divided the 3 days into 3 different blog posts, otherwise it would be extremely overwhelming and long. Our Professor Dr Robert Clayton created lab packets for our drive and for the hike. It was amazing traveling down to Arizona and seeing the landscape from a very different perspective. Dr. Clayton was in the same car as myself, so I got to hear learn from him as we drove down. This is a collection of a few of the photos I captured, most of which are specific geologic structures. Pardon the blurriness of the photos I was in a car most of the time.
I honestly don't know the Geologic structure here, but it sure is cool looking.
The Horizontial lines in this picture are ancient shore lines from Lake Bonneville. Lake Bonneville is a glacial lake from the last ice age. Here is a link for more information: Utah Geology
More old shore lines.
The homes in this picture are built on a land slide. Land slides are always land slides. So sadly in time these homes will no longer be there.
This is a volcano.
Oh look another volcano.
The pinnicales in this picture are of snadstone. The sandstone is fractured so weathering creates these fantastic structures. The same process is found in Bryce Canyon and Brians Head.
This has nothing to do with rocks, but the city placed a cop car with a dummy in it to scare drivers.
Cross bedding. After learning how to identify cross bedding we quickly became experts and pointed every cross bedded rock we could. This cross bedding was created by ancient sand dunes, the same as in Zion National Park.
LOOK! More cross bedding.
This is an example of a butte.
This is the Chinlee Formation. A shale rock body that weathers easily. As it weathers and erodes it forms very gentle slopes. In this case it looks like a giant patch of melting ice cream.
I took hunderds of photos and it would be ridiculous to include all of them in this blog. So here is the link to view them all:
Please feel free to take a few minutes and enjoy the pictures.
