The United States has 112 protected areas known as national monuments. The President of the United States can establish a national monument by executive order, and the United States Congress can by legislation. The Antiquities Act of 1906 authorized the president to proclaim "historic landmarks, historic and prehistoric structures, and other objects of historic or scientific interest" as national monuments. Concerns about protecting mostly prehistoric Indian ruins and artifacts—collectively termed antiquities—on western federal lands prompted the legislation. Its purpose was to allow the president to quickly preserve public land without waiting for legislation to pass through an unconcerned Congress. The ultimate goal was to protect all historic and prehistoric sites on U.S. federal lands.
President Theodore Roosevelt established the first national monument, Devils Tower in Wyoming, on September 24, 1906. He established eighteen national monuments, although only nine still retain that designation. Sixteen presidents have created national monuments since the program began; only Richard Nixon did not. Bill Clinton created the most monuments, nineteen, and expanded three others. Jimmy Carter protected vast parts of Alaska, proclaiming fifteen national monuments, some of which later were promoted to national parks. The most recent national monument designated by Presidential Proclamation was by Barack Obama on October 8, 2012 (César E. Chávez National Monument).
Twenty-seven states have national monuments, as do the District of Columbia, the Virgin Islands, American Samoa, the Minor Outlying Islands, and the Northern Mariana Islands. Arizona, with eighteen, has the largest number of national monuments, followed by New Mexico with twelve and California with eleven. Fifty-five national monuments protect places of natural significance, including ten geological sites, seven marine sites, and five volcanic sites. Twenty-two national monuments are associated with Native Americans. Twenty-four are other historical sites, including twelve forts.
Many national monuments are no longer designated as such. Some were changed to national parks or another status by Congress or the President, while others were transferred to state control or disbanded.
Famous quotes containing the words united states, national, monuments, united and/or states:
“Why doesn’t the United States take over the monarchy and unite with England? England does have important assets. Naturally the longer you wait, the more they will dwindle. At least you could use it for a summer resort instead of Maine.”
—W.H. (Wystan Hugh)
“Ignorance, forgetfulness, or contempt of the rights of man are the only causes of public misfortunes and of the corruption of governments.”
—French National Assembly. Declaration of the Rights of Man (drafted and discussed Aug. 1789, published Sept. 1791)
“If the Revolution has the right to destroy bridges and art monuments whenever necessary, it will stop still less from laying its hand on any tendency in art which, no matter how great its achievement in form, threatens to disintegrate the revolutionary environment or to arouse the internal forces of the Revolution, that is, the proletariat, the peasantry and the intelligentsia, to a hostile opposition to one another. Our standard is, clearly, political, imperative and intolerant.”
—Leon Trotsky (1879–1940)
“I thought it altogether proper that I should take a brief furlough from official duties at Washington to mingle with you here to-day as a comrade, because every President of the United States must realize that the strength of the Government, its defence in war, the army that is to muster under its banner when our Nation is assailed, is to be found here in the masses of our people.”
—Benjamin Harrison (1833–1901)
“My opinion is that the Northern states will manage somehow to muddle through.”
—John Bright (1811–1889)
