As a result, there is too little rain for almost the whole western half of the United States, which lies in the ,,rain shadow of the mountains. In a great part of that territory, therefore, farmers must depend on irrigation water from the snows or rains that are trapped by the mountains. One of the most important geographic boundaries in the United States 15 the 50-centimeter rainfall line, which runs north and south almost through the middle of the country. East of the line, farming is relatively easy, and the population is relatively large. West of the line, one finds man-made irrigation systems, dry-farming, grazing, and fewer people.
