The one is an area of size created by Congress upon the assumption that it is a supreme example of its kind and with the purpose of developing it for public occupancy and enjoyment. The other is made by presidential proclamation to conserve an area or object which is historically, ethnologically, or scientifically important. Size is not considered, and development is not contemplated. The distinction is often lost in practice. Casa Grande is essentially a national monument, but had the status of a national park until 1918. The Grand Canyon, from every point of view a national park, was created a national monument and remained such until 1919. THE GRANITE NATIONAL PARKS GRANITE'S PART IN SCENERY The granite national parks are Yosemite, Sequoia, including the proposed Roosevelt Park, General Grant, Rocky Mountain, and Mount McKinley. Granite, as its name denotes, is granular in texture and appearance. It is crystalline, which means that it is imperfectly crystallized. It is composed of quartz, feldspar, and mica in varying proportions, and includes several common varieties which mineralogists distinguish scientifically by separate names.
