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.

On Monday, June 11, Secretary of the Interior Ken Salazar will participate in a ceremony to begin removal of the Great Works Dam on the Penobscot River in Maine – a major step toward enabling the river to flow freely from Old Town to the Gulf of Maine for the first time in generations.
The Penobscot River Restoration Project is a landscape-level conservation effort that will return endangered Atlantic salmon to their historic spawning ground, support hydropower production, and restore a Tribal Nation's connection to their cultural heritage. The project is one of 50 river projects from across the nation highlighted by Salazar as a model for community-driven river restoration.
In the afternoon, Salazar will hold a press conference at the L.L. Bean Flagship Store in Freeport, Maine. Along with the National Park Foundation, the official non-profit of America's national parks, and L.L. Bean, Salazar will provide an update on the year-long Million Moment Mission. A celebration of the company's 100-year anniversary, L.L. Bean has committed $1 million to the National Park Foundation's “America's Best Idea” program in support of efforts to increase children's opportunities to spend time outdoors.
