The Chicago Tribune has assembled a brief photoessay highlighting the 20 National Monuments receiving the fewest visitors in 2009, based on National Park Service data. The "winner," with only 14 visitors for the whole year, was Aniakchak, Alaska (pictured above):
No roads will take you to Aniakchak National Monument and Preserve, on the Alaskan peninsula 450 miles southwest of Anchorage. To access this park you'll need to hire an air taxi or a power boat. The park encompasses a 6-mile-wide, 2,000-foot-deep caldera formed by the collapse of a 7,000-foot mountain and offers visitors a taste of one of the wildest terrains in Alaska.
About half of the others are in Arizona and New Mexico, but you can also find peace and quiet in National Monuments in the Virgin Islands, Missouri, Colorado, Idaho, Texas, Nebraska, Wyoming, Virginia, and Alabama. Details at the link.
