The ancient worn-down ridges of the southern Appalachians — some of the oldest mountains on Earth, and why they look and feel the way they do.
Take a good look at the shape of the country around you — these long, soft, endlessly folded green ridges, rolling off blue into the distance. They don't have the jagged, snow-capped drama of the Rockies or the Alps, and there's a wonderful reason for that: these are some of the oldest mountains on the entire planet.
The Appalachians were thrown up hundreds of millions of years ago, when whole continents collided — and back then they may have stood as tall and sharp as the Himalayas do today. But that was so long ago that time itself has worn them down. Hundreds of millions of years of rain and ice and root and river have rounded off every peak and softened every ridge into these gentle, ancient waves of stone. You're not looking at young, raw mountains. You're looking at the worn-down roots of an unimaginably older range — mountains so old they were already ancient before the dinosaurs walked.
And that great age is exactly why they're so rich. Undisturbed by glaciers and ice ages that scoured the north, these mountains became one of the most biologically diverse temperate places on Earth — more kinds of tree, of salamander, of wildflower than almost anywhere. So this soft, humble, blue-green country you're driving through isn't just pretty. It's a living museum, hundreds of millions of years in the making. Drive it gentle. It's earned some respect.
