What was the leopard seeking at that altitude?

Hemingway is a master storyteller. The first few lines in his short story, Snows of Kilimanjaro could be a story all by itself.

Kilimanjaro is a snow-covered mountain 19,710 feet high, and is said to be the highest mountain in Africa. Its western summit is called the Masai “Ngaje Ngai,” the House of God. Close to the western summit there is the dried and frozen carcass of a leopard. No one has explained what the leopard was seeking at that altitude.
