Mercury's surface in "enhanced color," a color scheme created to emphasize color differences. This is not what Mercury would look like to the human eye, but by applying mathematical analysis to images, color differences can be accentuated beyond those visible to a person.
Mount Rushmore National Memorial under construction.
The workers had to endure conditions that varied from blazing hot to bitterly cold and windy. Each day they climbed 700 stairs to the top of the mountain to punch-in on the time clock. Then 3/8 inch thick steel cables lowered them over the front of the 500-foot face of the mountain in a "bosun chair." Despite the dangers, no one was killed during the project.
Otters in Glacier Bay National Park and Preserve, Alaska.
The sea otter population of Glacier Bay has increased dramatically in the past 20 years. Ecologists consider sea otters a keystone species here. Otters consume vast quantities of clams, urchins, crabs, and other invertebrates and their presence creates ripples through the ecosystem. NPS photo.

With more than 80% of Americans living in urban areas, urban parks are more important than ever. The father of American landscape architecture, Frederick Law Olmsted, said of urban parks:
It is one great purpose of the Park to supply to the hundreds of thousands of tired workers, who have no opportunity to spend their summers in the country, a specimen of God's handiwork that shall be to them, inexpensively, what a month or two in the White Mountains or the Adirondacks is, at great cost, to those in easier circumstances.

WASHINGTON -- Secretary of the Interior Ken Salazar today announced that the United States is nominating Poverty Point State Historic Site and National Monument in West Carroll Parish, Louisiana, for inclusion on the World Heritage List. The nomination document was prepared by the State of Louisiana in consultation with the National Park Service's Office of International Affairs. The nomination has been submitted through the U.S. Department of State to the offices of the World Heritage Centre in Paris, France.
If approved by the World Heritage Committee, the prehistoric earthworks would join the Taj Mahal, the Statue of Liberty, Stonehenge, the Grand Canyon and the Great Barrier Reef on the list of 962 sites in 157 countries designated as the most significant cultural and natural sites on the planet.
“Tucked into the bayous of Louisiana, the Poverty Point earthworks are the remarkable legacy of a prehistoric hunter-gatherer society that existed thousands of years ago,” Salazar said. “Designation as a World Heritage Site not only would be an honor for both Louisiana and the United States but also would be an invitation to domestic and international travelers, helping to accomplish the goals of President Obama's National Travel and Tourism Strategy to generate jobs through increased tourism.”
“We thank the State Department and the State of Louisiana for their partnership on the nomination of Poverty Point to be a World Heritage Site,” said Acting Assistant Secretary for Fish and Wildlife and Parks Rachel Jacobson. “Poverty Point is a significant cultural site that is certainly deserving of recognition on the world stage.”
“Designation as a World Heritage Site is how the international community shines a light on the places that should be special to all of us,” said National Park Service Director Jonathan B. Jarvis. “This nomination of Poverty Point earthwork is an important way to share what we value as a people, the places that define our society.”
“We are thrilled that Poverty Point is being nominated by the National Park Service to be added to the prestigious list of World Heritage Sites,” Lt. Governor Dardenne said. “Before there was a Great Wall of China there was Poverty Point which offers visitors a unique look into America's earliest civilization telling the story of a complex society living off Louisiana's fertile land. We are hopeful that this nomination not only will attract visitors from across the globe but also will create jobs and spur the economy of northeast Louisiana.”
Located in northeastern Louisiana on a bayou of the Mississippi, Poverty Point is a vast, integrated complex of earthen monuments, constructed 3,100 – 3,700 years ago. It consists of six enormous, concentric earthen ridges with an outer diameter of more than a half mile, and several large mounds, including one of the largest in North America.
This constructed landscape was the largest and most elaborate of its time on the continent; the particular form of the complex is not duplicated anywhere else in the world. The site is especially notable because it was built by a settlement of hunter-gatherers, not an agricultural society.
The UNESCO World Heritage List is part of the World Heritage Convention, an international treaty signed by 190 countries for natural site conservation and cultural site preservation first proposed by the United States government in 1972.
After reviews by World Heritage Centre staff and by the International Council for Monuments and Sites (ICOMOS), it will be considered for inscription on the World Heritage List by the World Heritage Committee, which is a rotating body of 21 nations elected from among the signatories of the World Heritage Convention.
Inscription as a World Heritage Site does not impose any legal restrictions on property owners or neighbors of sites, nor does it give the United Nations any management authority or ownership rights in U.S. World Heritage Sites, which continue to be subject only to existing federal and local laws. The agreement of the property owner is required by U.S. law in order for a site in this country to be nominated to the World Heritage List.
Two other potential nominations of U.S. sites are now in development: the San Antonio Franciscan Missions in Texas, and eleven buildings of Frank Lloyd Wright located throughout the U.S.
