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.
Secretary Salazar, Deputy Secretary Hayes, BSEE Director Watson to Visit Norway for Ministerial Forum on Offshore Energy Safety
Office of the Secretary
WASHINGTON – Secretary of the Interior Ken Salazar will travel to Trondheim, Norway, on June 25-28 to continue his ongoing dialogue with international counterparts, government officials and oil and gas industry leaders regarding the safe and responsible development of offshore energy resources.
The discussions and meetings Secretary Salazar will hold in Norway, at the invitation of Norwegian Minister of Petroleum and Energy Ola Borten Moe, are geared toward informing the Obama administration's goals of expanded safe and responsible production of our domestic resources while ensuring the strongest possible safety and environmental oversight of offshore oil and gas activities on the U.S. Outer Continental Shelf.
In response to the Deepwater Horizon explosion and resulting oil spill in the Gulf of Mexico, the Obama administration undertook the most aggressive and comprehensive reforms to offshore oil and gas regulation and oversight in U.S. history. As part of a shared commitment to reduce the risks associated with offshore drilling around the world, Secretary Salazar will meet with ministers and senior government officials from nations engaged in offshore oil and gas operations to discuss these historic reforms and share best practices and lessons learned in offshore oil and gas development, including in the Arctic.
Secretary Salazar will be joined by a U.S. delegation including Deputy Secretary David J. Hayes and Bureau of Safety and Environmental Enforcement Director James A. Watson. Their trip will include a visit to an offshore oil facility and a roundtable discussion on sustainable Arctic energy development with international counterparts and other officials and stakeholders.
The trip builds on last year's Ministerial Forum on Offshore Drilling Containment, hosted by Secretary Salazar in Washington, D.C., which included interactive discussions on well containment and lessons learned from the Deepwater Horizon oil spill.
