Utah: Postcard Friendship Friday


This is an oversized postcard (8 inches by 6 inches) published by the Utah Geological Survey. I really like geology and pick these up when I can. When I send them through Postcrossing, the recipients just love them.


On the left is a geological map of Utah. Each color represents different rock that is exposed at the surface, or near the surface, just covered by soil. Without an explanation the colors mean very little so there is a key in the upper right. Here, different colors represent rocks of different ages. Yes, there is standard color scheme! Yellows are most recent rocks, or sediments recently deposited by rivers. Greens and aqua are Mesozoic rocks (time of the dinosaurs). Blue, gray-blue to brown colors are the older rocks (Paleozoic). Igneous rocks of what ever age get their own bright colors: reds, pinks, magenta. They really liven up a geologic map!


The lower right contains a cross section, as if you cut through the ground, took half away, and saw what was inside. Older rocks are on the bottom, younger on the top, as you might expect.The geology under Utah leads to amazing landscapes. Utah is the home of Bryce and Zion, also Arches National Park and many others. In the north are beautiful mountains and wonderful ski areas.


Happy Postcard Friendship Friday! Check out Marie's site for more.

I can see why this type of postcard is so popular with the PostCrossing group - I've clicked to enlarge it several times! It's fascinating :) Thanks so much!

This is the first time I've seen a map postcard with a geological theme - and you've done a great job explaining it!
I'm going to keep an eye out now for this type of card. I'm not a Postcrosser (yet!) but I find one for you I'll pass it along!

Looking at it from this perspective it's hard to believe that Utah is habitable. This is a great card.

8x6, you say? that's a humongous postcard, indeed! capable of leaving humongous smiles on postcrossing recipients!

A salty place.

I've seen postcards much longer than 8 x 6.

Beverley Baird said...

What an awesome card. Thanks for all the info as well. I have never been to Utah -altho I have been to the Rockies in Western Canada.
Thanks for stopping by!
Take care and happy PFF!

For some reason I always have problems posting on this format and usually lose my messages. I think that the postcard and the info you provided are wonderful and fascinating. I also checked some of the postcard links you provided and enrolled in postcrossing. I thank you for that because I love getting snail mail. I have a drawer full of unused postcard and a shelf of received postcards. I'll have fun!!

Then I think you will enjoy postcrossing very much. Getting a card from Finland or somewhere(along with bills)is a thrill. You'll see there are many Finns on postcrossing!

Since I've started paying more attention to postcards, I'm amazed at how much you can learn from them - the colors in this one are so pretty and eye catching too. Happy post Fourth of July!

This postcard really impressed to me, I never have seen something similar, and their content is original. I'm so glad to find it, and to find your blog too. Also I wanna add something ells, and it's the big quantity of viagra online that I've had to elude since I've search idealistic blogs.
