Blinding snowstorms erase landmarks and leave travelers lost in the wilderness.

Evidence

The storm was very severe, and the landmarks being blotted out, I lost my way in the snow, and when I reached the cabin after dark I found it still empty, for the two hunters, on returning, finding that I had gone out, had gone in search of me. The snow cleared off late, and intense frost set in. — Isabella L. Bird, A Lady’s Life in the Rocky Mountains, 226
