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.
Salazar Applauds President Obama's Intent to Nominate Dr. Marcia McNutt as Director of the U.S. Geological Survey

WASHINGTON, D.C.—Secretary of the Interior Ken Salazar today praised President Obama's announcement that he intends to nominate Dr. Marcia McNutt as Director of the U.S. Geological Survey (USGS) and Science Advisor to the Secretary. She would be the first woman director of the agency since its establishment in 1879. The nomination is subject to Senate confirmation.
Dr. McNutt currently serves as President and Chief Executive Officer of the Monterey Bay Aquarium Research Institute in California. She worked for USGS, the agency that she would direct, at the start of her career.
“We look forward to welcoming Dr. McNutt, who is now a world-class scientist, back to the U.S. Geological Survey,” Secretary Salazar said. “Not only does she offer sterling academic credentials, but she also has worked in the field as chief scientist on many oceanographic expeditions and has been involved in government as chair of the President's Panel on Ocean Exploration convened by President Clinton. Her experience will be valuable in leading the government's premiere scientific agency.”
Dr. Marcia McNutt studied geophysics at Scripps Institution of Oceanography in La Jolla, California and earned her PhD there in Earth Sciences in 1978. She then spent three years with the USGS in Menlo Park, Calif. working on earthquake prediction.
Dr. McNutt joined the faculty at MIT in 1982 where she became the Griswold Professor of Geophysics and served as Director of the Joint Program in Oceanography & Applied Ocean Science & Engineering, offered by MIT & the Woods Hole Oceanography Institution.
McNutt has participated in 15 major oceanographic expeditions and served as chief scientist on more than half of those voyages. She has published 90 peer-reviewed scientific articles. Her research has ranged from studies of ocean island volcanism in French Polynesia to continental break-up in the Western United States to uplift of the Tibet Plateau.
She served as President of the American Geophysical Union from 2000-2002. She was Chair of the Board of Governors for Joint Oceanographic Institutions, helping to bring about its merger with the Consortium for Ocean Research and Education to become the Consortium for Ocean Leadership, for which she served as Trustee. She is a fellow of the American Geophysical Union, the Geological Society of America, the American Association for the Advancement of Science and the International Association of Geodesy.
Dr. McNutt's honors and awards include membership in the National Academy of Sciences, the American Philosophical Society and the American Academy of Arts and Sciences. She serves on numerous evaluation and advisory boards for institutions such as the Monterey Bay Aquarium, Stanford University, Harvard University and Science Magazine
