Author David Quammen writes about an extraordinary experience among the elephants of Samburu National Reserve, Kenya. Late one afternoon, biologist lain Douglas Hamilton stopped by my tent and asked if wanted to drive out and see some elephants before sunset. I asked him if he would like to take a walk instead. I knew that walking around the reserve could be risky, but surely we could at least climb the little hill just behind camp. He agreed, and we did. The view of the river from the top was magnificent. Just north of us was a larger hill known as Sleeping Elephant. I asked him if he had ever climbed that one. He told me he hadn't, but, with mischievous look in his eye, that we could.
