Facts About Colorado:
Colorado lies between 37 and 41 north latitude, and 102 and109 west longitude. Its breadth is 276 miles; the length of its southern boundary is 387 miles, and of its north boundary 366 miles.
There are 18 forest reserves in the State, comprising over 22,000 square miles.
The coal area of Colorado exceeds 18,000 square miles, or about 17 per cent of the total area, 103,948 square miles.
The gold district of Colorado embraces about 20 counties in the central and western mountains part of the State. Silver is distributed in places within the same area. Some gold and silver ores carry lead and copper in varying quantities.
The eastern third of Colorado is composed of high plains; the middle third, of the Rocky Mountains; and the western third, of plateaus and valleys sloping uneverly toward the Utah line.
The principal mountain chains are Front Range, Park Range, Sawatch Range, San Juan Range, and Sangre de Cristo Range. The Continental Divide jumps from one range to another, varying in elevation from 10,000 feet to 14,436 feet above sea level.
The largest river in Colorado is the Grand; the second largest, the Arkansas; the third largest, the South Platte; the fourth largest, the Gunnison.
The mean temperature at elevations between 4,000 and 6,000 feet is from 48 to 54 degrees, which is about the same as that in Maryland, western Virginia, central France, central Turkey in Europe, northern Japan, and northern California on the coast.
The average annual precipitation is about 16 inches. The plains region is semi-arid, the average annual rainfall ranging from 10 to 18 inches. The rainfall on the western slope runs from 8 to 19 inches.
The mountains have more rain and snow than the plains. The average annual precipitation in the Rockies is from 15 to 40 inches, depending on the locality. The snowfall on Front Range is heavier on the western slope. The maximum depth of snow is said to be near timberline, just above 11,000 feet. In the mountain districts snow falls during nine months of the year.
The percentage of possible sunshine varies at different points in the State from 65 to 80.
