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.

DENVER, CO—On Friday, May 4, 2012, Secretary of the Interior Ken Salazar and Colorado Governor John Hickenlooper will announce the next steps in implementing conservation and recreation projects throughout the Denver metropolitan area and along the South Platte River, including the Rocky Mountain Greenway Project.
Last May, Gov. Hickenlooper and Sec. Salazar announced three conservation initiatives in Colorado as part of the America's Great Outdoors Initiative, a nationwide effort to encourage and support community-driven conservation and recreation projects around the country. On Friday, they will host a meeting with elected officials, local and regional planners, and other open space leaders throughout the metropolitan area to discuss the initiatives' ongoing progress.
The Rocky Mountain Greenway Project focuses on a federal, state, local and stakeholder partnership to enhance the Denver metropolitan area parks, open spaces, river corridors and trails—creating an uninterrupted trails/transportation link connecting the Denver metro area's trail systems, the three National Wildlife Refuges in the metro region, Rocky Mountain National Park, and community trails systems in between.
Sec. Salazar and Gov. Hickenlooper will also be joined by Senator Mark Udall, Congressman Ed Perlmutter and Denver Mayor Michael B. Hancock to unveil a Colorado Department of Transportation directional sign for the Rocky Mountain Arsenal National Wildlife Refuge. A former chemical weapons manufacturing facility, the site has since been transformed into an urban gateway and sanctuary for residents, visitors and wildlife. The sign is part of an effort to increase the refuge's visibility and encourage more visitors.
