Monumental Places
If you're grateful that the Grand Canyon, Glacier Bay, and the Olympic Peninsula have been preserved as national parks, consider that these icons were once national monuments. The Antiquities Act of 1906 allows the president to proclaim areas of "historical or scientific interest" as national monuments, using a signature alone. The first to receive the honor was Devils Tower in Wyoming, designated by Theodore Roosevelt in 1906. One of the most recent is Berryessa Snow Mountain (second slide), protected in 2015 by Barack Obama, who also protected Fort Ord (below) along the California coast in 2012, and New Mexico's Organ Mountain-Desert Peaks in 2014 (third slide). And the largest national monument is a marine sanctuary near Hawaii, established by George W. Bush in 2006. (Only three presidents since Roosevelt have not established a monument.)
