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.

Las Vegas, Nev. -- On Tuesday, October 19, 2010, Secretary of the Interior Ken Salazar and Senator Harry Reid will celebrate the groundbreaking of the Southwest Intertie Project (SWIP), a major transmission line whose construction will create jobs, spur growth in the renewable energy sector, and improve transmission capacity for Western communities. The Secretary will be joined by the Chief Executive Officers (CEO) for LS Power and NV Energy, along with Jonathan Silver of the Department of Energy.
The first phase of SWIP connecting Southern Nevada with Northern Nevada (to be known as ON Line) is expected to begin construction in 2010 and achieve commercial operation in 2012. The complete SWIP is a proposed, above-ground 515-mile, 500 kilovolt (“kV”), transmission line stretching from Idaho to Southern Nevada that will provide up to 2,000 megawatts (“MW”) of transmission capacity for Nevada and the Western Electric Grid.
