In this passage, London describes the setting for this story. Read the passage, then answer the question.

The man looked along the way he had come. The Yukon lay a mile wide and hidden under three feet of ice. On top of this ice were as many feet of snow. It was all pure white. North and south, as far as his eye could see, it was unbroken white. The one thing that relieved the whiteness was a thin dark line that curved from the pine-covered island to the south. It curved into the north, where it disappeared behind another pine-covered island. This dark line was the trail—the main trail. It led south 500 miles to the Chilcoot Pass, and salt water. It led north 75 miles to Dawson, and still farther on to the north a thousand miles to Nulato, and finally to St. Michael, on Bering Sea, a thousand miles and half a thousand more.
