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.

WASHINGTON, D.C. – Secretary of the Interior Ken Salazar today told the Presidential commission investigating the Deepwater Horizon oil spill that the tragedy has fueled and bolstered the Department's ongoing drive to reform and restructure the federal offshore oil and gas regulatory framework and to make the nation a world leader in safe and environmentally responsible energy development.
“It is my goal for the Department of the Interior, with the help of this Commission, to create the gold standard for worker safety and environmental protection in oil and gas production in the oceans of America,” Secretary Salazar told the National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling. “These standards will serve as a model for the world so that other nations too can learn from the tragedy of the Deepwater Horizon oil spill.”
Secretary Salazar was joined at the meeting by Interior Deputy Secretary David J. Hayes and Michael R. Bromwich, Director of Interior's Bureau of Ocean Energy Management, Regulation and Enforcement (BOEM).
Secretary Salazar's testimony covered the Department's immediate response efforts, ongoing reform and restructuring of offshore oil and gas regulations, continuing recovery efforts and environmental damage assessments and policy on offshore oil and gas development in the Arctic.
