CARVING THE MOUNTAINS:

At the time they formed, the Appalachians were much higher than they are today — more like the present-day Rocky Mountains. While the Atlantic Ocean was still in its infancy, the Appalachians were already being attacked by erosion. For the last 100 million years, erosion has carved away the mountains, leaving only their cores standing. Erosion continues today and is constantly altering the landscape of the Southern Appalachians.

Four times during the past 2 million to 3 million years, great sheets of ice advanced steadily southward from the polar region. The glaciers did not extend as far south as the Southern Appalachians, but they triggered a change in climate that can be seen today in both the rocks and the life of the region.

What a meditation on sense of time! Were the Appalachians really that tall once upon a time?

I had an acquaintance who climbed it years ago and lived (to tell the tale. Merry Christmas to you and your tribe!
