Here are several versions of an aerial photo (#2991) taken during a 1973 survey of Northern Botswana. The photo depicts a small area (4.4 x 4.4 miles) near the center of the Okavango Delta and includes the home ranges of the two baboon groups that I studied from 1977 to 1980.
I thank Rabindra Das and the Director, Department of Surveys and Mapping, Ministry of Lands and Housing, Government of Botswana for kindly permitting me to post this photo here.
