Where did Tim white find the 4.4 million year old hominid in 1974?

In 1974 he worked with Mary Leaky and in 1976 the team he was on discovered fossil footprints of an ancient hominid. This work was done in Kenya, Africa.
Later he assisted Donald Johanson in analyzing the fossil skeleton known as "Lucy." White was a listed author, along with Johanson, of the 1978 paper that announced their finding that Lucy was not a specimen of Australopithecus africanus but a different species they named Australopithecus afarensis. Lucy's remains were found in Ethiopia.

At 3.2 million years of age, Lucy's was the oldest nearly complete hominid skeleton to come to light up to that time.

In 1992 the team he now lead found a layer of 4.4 million-year-old sediment with bones of around 17 individuals. Which were 2 million years older than Lucy. These were found in Addis Ababa, Ethiopia. They named the groups as if it were one, called Ardi.

White said that the specimens belonged to a different genus, he it named Ardipithecus ( ground ape) as opposed to the tree-dwelling apes of today. These hominids are now known as Ardipithecus ramidus.

While Lucy was exclusively bipedal, Ardi was capable of walking both upright and on all fours. Her hands were flexible for a variety of tasks, but suitable for walking on all fours.
While modern apes walk with their weight on their knuckles, Ardi would have walked with her weight resting on the palms of her hands.

The jaws of A. ramidus males lacked the large canine teeth that chimpanzees and other apes
use to express aggression, particularly when competing with other males for access to females.
It has been said that this made a male less aggressive but more providing as he would walk upright and carry items as well.
