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.

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.

Every day someone like you becomes a wildland wildfire fighter, a teacher, a trail-builder, a museum curator, or a park ranger. Discover your opportunities in national parks. Come to play. Come to learn. Come to serve. Develop your environmental leadership skills. Find a job. Be the next generation to preserve and protect these great places.
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.
Salazar, Lubchenco Applaud Designation of Papahanaumokuakea Marine National Monument as a World Heritage Site

WASHINGTON — Secretary of the Interior Ken Salazar and NOAA Administrator Dr. Jane Lubchenco today commended the World Heritage Committee for adding Papahanaumokuakea Marine National Monument (Papahanaumokuakea) in the Northwestern Hawaiian Islands to the prestigious UNESCO World Heritage List at its annual meeting in Brasilia, Brazil. Measuring nearly 140,000 square miles and protecting more than 7,000 marine and terrestrial species, Papahanaumokuakea is the nation's first site designated for its outstanding value as both a natural and cultural heritage site.
World Heritage listing acknowledges the historical, cultural or natural value of a site, as well as the commitment of the sovereign nation and the site's owners to its long-term protection and management.
“I am pleased that the World Heritage Committee recognized the unique cultural and natural heritage of Papahanaumokuakea Marine National Monument and the commitment of the United States and the state of Hawai'i to conserve it,” Salazar said. “The monument will now be part of an exclusive list that includes sites such as the Egyptian pyramids, the Taj Mahal, and the Great Barrier Reef.”
“We are proud to add this exceptional marine protected area to the list of the world's greatest natural and cultural treasures,” said Dr. Lubchenco, under secretary of commerce for oceans and atmosphere and NOAA administrator. “As the nation's first primarily marine World Heritage site, Papahanaumokuakea helps forward global recognition of the critical heritage values of the sea and global understanding of the importance of protecting our oceans.”
The islands and seascape were inscribed as a spectacular example of evolution in isolation, resulting in a great number of marine and terrestrial flora and fauna unique to Papahanaumokuakea. The tiny islands and atolls provide nesting and foraging grounds for 14 million seabirds, making it the world's largest tropical seabird rookery. Sharks and other large apex predators are abundant in the waters of Papahanaumokuakea. Additionally, the region provides the only remaining habitat for several endangered species, such as the Laysan duck and Nihoa millerbird and provides critical habitat for the Hawaiian monk seal.
Geologically, the monument is an unparalleled example of volcanic island and atoll formation, stretching over 1,200 miles from end to end.
Papahanaumokuakea is the name given to this area of the Northwestern Hawaiian Islands by the Monument's Native Hawaiian advisory group, honoring its deep cultural significance to the indigenous people. Two of the islands in Papahanaumokuakea feature the highest concentrations of ritual sites in Hawai‘i and bear remarkable testimony to the shared historical origins of Polynesian societies. In predominant Native Hawaiian tradition, Papahanaumokuakea is believed to lie within the place where life originates and to which it returns.
Papahanaumokuakea Marine National Monument is administered jointly by the Department of the Interior as a component of the National Wildlife Refuge System, the Department of Commerce, and the State of Hawai‘i, with assistance from the Office of Hawaiian Affairs. World Heritage designation does not change the Monument's management structure and Papahanaumokuakea will continue to be managed to ensure the conservation and preservation of the Monument's relatively pristine ecosystems and significant cultural heritage for future generations.
The United States nominated the monument as a World Heritage site in 2009. The remote chain of atolls and surrounding waters is the first U.S. site to be added to the World Heritage List in 15 years. It joins 20 U.S. sites currently on the list, including the Grand Canyon and the Statue of Liberty.
In 2009 the World Heritage List had 878 sites from 144 countries, including 679 cultural, 174 natural, and only 25 mixed natural and cultural sites.
