The Simien Mountains in Ethiopia's north are swarming with Gelada baboons (which aren't actually baboons). Below are some photos I took of them over Thanksgiving break:
And an interesting fact about the mountains, from Wikipedia:
Although the word Semien means "north" in Amharic, according to Richard Pankhurst the ancestral form of the word actually meant "south" in Ge'ez, because the mountains lay to the south of Aksum, which was at the time the center of Ethiopian civilization. But as over the following centuries the center of Ethiopian civilization itself moved to the south, these mountains came to be thought of as lying to the north, and the meaning of the word likewise changed.
