Description: This map is one of the earliest weather maps of the United States, which traced an 1859 storm across the continent. Manuscript annotations in red ink show dates and positions of the storm front. The base map was prepared for the Boston Society of Natural History by William C. Cleveland; and shows isothermal lines of mean temperatures. The lower right margin reads: "American Photo-Lithographic Co., Osborne's Process."
