The rift valley escarpment is drained by a number of small streams that ultimately flow down into the lake. These were often quite beautiful. High atop the rift valley escarpment, Lake Manyara Hotel was visible. But, Njau told us that Kirurumu has better service. We found some baboons digging through elephant dung for food.
Elephants have such inefficient digestive systems that much food passes through undigested.
This is great for seeds, etc., as they pass through the elephant's digestive system. Their hulls are softened by the digestive process. They then find themselves in a rich growth medium where they can sprout. The dung also attracts insects. It is these seeds and insects the baboons are looking for.
