This is why most glaciers are found either in mountainous areas or the polar regions. However, snow line occurs at different altitudes: in Washington State the snow line is around 1,600 meters (5,500 feet), while in Africa it is over 5,100 meters (16,732 feet), and in Antarctica it is at sea level.
Ninety-five percent of all beer and soft drink cans in the United States are made of aluminum. American can makers produce about 100 billion aluminum beverage cans a year, equivalent to one can per American per day. While almost all food cans are made of steel, aluminum's unique properties make it ideal for holding carbonated beverages. The typical aluminum can weighs less than half an ounce, yet its thin walls withstand more than 90 pounds of pressure per square inch exerted by the carbon dioxide in beer and soft drinks.
We also have a partnership with Ball Corp. to operate an end production plant and the nationâs largest aluminum can manufacturing plant, in Golden (Rocky Mountain Metal Container, 340 employees), and a partnership with Owens-Illinois to make glass bottles in nearby Wheat Ridge (Rocky Mountain Bottle Co., 250 employees).
