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.
Salazar Announces Next Phase of Improvements to Access, Visitor Safety, Experience at Statue of Liberty
Office of the Secretary
Liberty Island to Remain Open during Statue's Year-Long Renovation
New York, NY -- Secretary of the Interior Ken Salazar today announced that the Statue of Liberty National Monument and Ellis Island will undergo a $27.25 million renovation that includes long-planned safety and other critical facility renovations beginning in late October.
“Two years ago, when we reopened Lady Liberty's crown to visitors for the first time since the September 11 attacks, I promised that we would continue to upgrade the interior to make it safer and more accessible for all,” Salazar said. “With today's announcement, we are taking a major step in bringing a 19th Century icon into the 21st Century.”
The National Park Service awarded the work to Joseph A. Natoli Construction Corporation of Pine Brook, NJ, to install code compliant stairways within the monument, update mechanical, electrical and fire suppression systems, replace the elevators, and rehabilitate restrooms. The improvements will also allow for increased visitor access to the monument, including the pedestal and the museum.
The National Park Service will keep the monument open to the public through the Oct. 28 celebration of the 125th anniversary of the statue's dedication. It will be closed the following day as work commences; however, Liberty Island will remain open during the project and views of Lady Liberty will remain largely unobstructed during the year-long upgrade to the statue's interior.
Secretary Salazar re-opened the crown of the Statue of Liberty to visitors on July 4, 2009 after it was closed following the 9/11 attacks for safety and security reasons. For safety considerations, the National Park Service has to limit the number of visitors to the crown to groups of no more than 10 visitors at a time. With approximately three groups ascending the crown per hour, an average of 240 visitors climb to the crown each day.
National Park Rangers will remain on site to provide interpretation to Statue of Liberty visitors, most of whom tour only the outdoor grounds of Liberty Island, with only a small percentage securing a reservation for entry into the monument. Approximately 3.5 million people visit every year.
The project is funded through a combination of National Park Service appropriations and the park Concession Franchise Fee program.
A gift from France, the Statue of Liberty was dedicated on October 28, 1886, designated as a National Monument in 1924, inscribed as a World Heritage Site in 1984 and restored for her centennial on July 4, 1986.
