I am NOT going out shopping on Black Friday. We are decorating for Christmas. Which has little to do with the state of Idaho, but that is the postcard for today.
This is standard sized postcard, published by the Idaho Geological Survey. After scanning it, I seemed to have misplaced it!
The Geology of Idaho is similar to the states around it - after all, geology does not stop at the state line. The pink color represents a huge intrusion of granite, now exposed at the surface. The green and olive colors represent sedimentary rocks, uplifted during mountain building, just as in Montana, and Nevada. The bright blue represents Columbia River basalts. The broad yellow is another basalt flow. This area has developed good soils for growing potatoes.
Time to go, the kids are fighting. Happy PFF!

I absolutely adore this map--I love visiting the state of Idaho. Happy PFF!
The lower right section looks very much like camo-print. I used to live in the sedimentary rock part of this state in a place made famous by the Idaho Spud candy bar...a geological-looking chocolate marshmallow covered with chocolate and coconut.
I am becoming jealous of your geology postcards. A great reason to visit on PFF!
Happy Day After Thanksgiving.
I see Montana is sticking his nose in Idaho again...
I hope you had a good time decorating for Christmas! My education continues - I've heard of the potato growing in Idaho, and now I can relate it to the geology.
Never been to Idaho... but I do know that's where we get our potatoes! Thanks for sharing the geology! I didn't shop of Black Friday eaither! :)
