I-40 East, North Carolina (stretch between Knoxville TN and Asheville NC). Ok, so what?
40 was squeezing to one lane ahead. Creeping along 5-10 mph -- first time in a couple trips through here (beautiful drive in fall btw .. but so curvy ya gotta watch the road).
This is the foothills of the Appalachians region. What are mountains? Great big rocks essentially. Appalachians were Himalaya-sized 300-400 million years ago (think Mt Everest, K2, etc) -- now not so much.
If you were to the strip the vegetation ... as some of the roadcuts have done .. the rocks are exposed.
The last photos are the same, but on one ti show the layering/folding when Africa crashed into NorthAmerica and plowed up the Appalachians .. and the stratification of the ancient seafloor of what became the Atlantic Ocean (Part Deux .. its opened and closed twice, now opening for the THIRD time in 4 billions years or so)
Much better places to see this all along I-40, I-81, even I-75 between Knoxville and Cincinnati. Big road projects along where they are cutting back the roadcuts due to semi-truck sized rocks coming down and smashing things.
Maryland, Virginia, Pennsylvania, West VA .. hard for me to watch road due to the fascinations right outside the window.
I like geology. Always have. Enough ranting
