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.

Policy Management and Budget
The Department of the Interior today hosted an Alaska science workshop, bringing together top federal policymakers and members of the federal government's science community to discuss how to facilitate the delivery of relevant scientific information to officials responsible for making decisions related to energy development in Alaska.
Led by Deputy Secretary David J. Hayes and Fran Ulmer, Chair of the U.S. Arctic Research Commission and former chancellor of the University of Alaska, Anchorage, today's meeting reflects a commitment to ensuring that decisions about the nation's domestic energy resources in Alaska are being made based on the best available science. The meeting was organized as part of the activities of the high-level federal interagency working group established in July by President Obama to coordinate energy development in Alaska and chaired by Deputy Secretary Hayes.
“Alaska's energy resources – onshore and offshore, conventional and renewable - hold great promise and economic opportunity for the people of Alaska and across the nation,” said Deputy Secretary Hayes. “We know that a ‘one-size-fits-all' approach doesn't work when it comes to Alaska, and we will continue to pursue sound, science-based decisions about the safe and responsible development of Alaska's energy resources.”
Other meeting participants included high-level officials and scientists from the Department of Interior including Bureau of Ocean Energy Management Director Tommy P. Beaudreau, as well as from the Departments of Defense, Commerce, Agriculture, Energy, Homeland Security, the Environmental Protection Agency, the Office of the Federal Coordinator for Alaska Natural Gas Transportation Projects, the White House's Office of Science and Technology Policy, and the Executive Office of the President. Also participating were senior representatives from the U.S. Arctic Research Commission and the Interagency Arctic Research Policy Committee.
The discussion focused on issues relating to energy and infrastructure development in Alaska, the types of scientific information that is needed to support decisions in this area, and the best ways to improve communication between decision-makers and the scientific community.
This dialogue is part of the Administration's commitment to continuing the expansion of safe and responsible production of our domestic resources.
