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.
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.

BOSTON – On Friday, May 25, Secretary of the Interior Ken Salazar will join Boston Mayor Thomas M. Menino and other dignitaries to dedicate the new visitor center at Faneuil Hall, the site of events important to American history including the American Revolution and the Abolitionist Movement.
Boston National Historical Park already attracts more than 3 million visitors a year and supports more than 1,200 jobs in the local community. The new visitor center is expected to help increase visitor numbers and improve visitors' experiences.
The new enhanced facility - a collaboration between the city of Boston and the National Park Service - includes interactive exhibits, an audio visual orientation program, handicapped-accessible public restrooms, and a bookstore. The space is comprised of 7,400 square feet for visitor services and community meeting space.
Later on Friday, Salazar will join U.S. Representative Niki Tsongas for a tour of the Lowell National Historical Park where he will see first-hand how the Park has helped spur economic revitalization throughout the city of Lowell.
