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.
Interior and Energy Sign MOU to Spur Offshore Renewable Energy Projects
Office of the Secretary

WASHINGTON, DC - The Department of the Interior and the Department of Energy today announced a new Memorandum of Understanding (MOU) that will strengthen the working relationship between the two agencies on the future development of commercial renewable offshore energy projects on the U.S. Outer Continental Shelf (OCS).
“Renewable energy development holds great promise for our clean energy future and our economy,” said Secretary of the Interior Ken Salazar. “This joint framework with DOE will bring together resources and expertise from both agencies as we pursue the environmentally responsible development of these valuable renewable energy resources.”
“We have a major opportunity to tap the energy in waves and offshore wind. Increasing cooperation between our agencies will help make clean, renewable energy a reality," said Secretary Steven Chu.
Together, DOI and DOE will use this agreement to spur the development of future commercial-scale offshore wind and water energy projects. The wind and water resources off the United States' coasts offer a vast yet largely untapped energy potential. According to DOE's 20% Wind Energy by 2030 report, offshore wind alone has the potential to produce 54,000 megawatts by 2030. The MOU between DOI and DOE will facilitate the development of these domestic energy resources by pursuing priority leasing and efficient regulatory processes for sites with high, commercial-scale offshore wind and water power development potential.
The two agencies will exchange information on resources and technologies, conduct stakeholder engagements, and collaborate on research projects. These activities will augment the scientific and technical exchanges that already occur between the two Departments. By facilitating the development of offshore clean energy, this agreement will further the Obama Administration's goals of creating clean energy jobs, expanding the nation's renewable energy portfolio and easing America's reliance on fossil fuels.
The MOU states that within 30 days of its signing, an interagency working group will develop an Action Plan covering the following areas:
• Development of attainable deployment goals for offshore wind and marine and hydrokinetic energy on the OCS
