The Afar Triangle, in Eastern Africa, is a nearly barren rockscape at the junction of three pieces of the Earth's crust.
Centered about the Afar Depression, at 509 feet / 155 meters below sea level, this junction of tectonic ridges, known as the East African Rift, is splitting apart and pulling away.
The junction consists of the Arabian Plate to the North and East, and the African Plate to the West and South. The African Plate is subdividing into two new tectonic plates, or protoplates, known as the Nubian Plate and the Somali Plate.
Geologists believe the pulling apart of these plates will eventually form a new ocean basin.

With tangerine trees and marmalade skies
Somebody calls you, you answer quite slowly,
A girl with kaleidoscope eyes.
~ The Beatles
When you're riding in a time machine way far into the future, don't stick your elbow out the window, or it'll turn into a fossil.Lucy was a bipedal hominid about a meter tall with a small brain and a primitive face. Radiometric dating of the surrounding rocks suggest Lucy's age is about 3.2 million years.
