The skin of the Earth is the color of tar,
Ridged, freshly healed like the seams of a scar.
Through salt-spattered sky, a gray-winged gull sails;
Steam gently rises, the island exhales.
A power plant rests on porous basalt,
In spaces beneath, a dark final vault.
Carbon is cached with a strong crystal lock,
Ashes to ashes, rock back to rock.

East Africa’s rift valley is considered by many to be the cradle of humanity. In the Turkana region of northwest Kenya, researchers Christopher Lepre and Tanzhuo Liu of Columbia University’s Lamont-Doherty Earth Observatory are cooperating with colleagues to study questions of human evolution, from the creation of the earliest stone tools to climate swings that have affected developing civilizations. Startling new discoveries are coming from this region at a rapid pace. Here are images from a recent field expedition. READ THE FULL SCIENTIFIC STORY or WATCH A VIDEO
