Ted Kerasote introduces the setting in the first paragraph of his essay. He describes the scene to the reader, that the action is taking place in the Northeastern corner of Yellowstone Park in the hills above Soda Bottle Creek. He describes that it's an isolated area, if you left one road you would not come across another one for quite some time.
