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.
Secretaries Salazar and Chu Convene Federal, Industry Officials to Discuss Deepwater Blowout Containment
Office of the Secretary

WASHINGTON, D.C. – In remarks today at a joint Department of the Interior and Department of Energy forum, Secretary of the Interior Ken Salazar pledged that the U.S. Government will be fully engaged in the effort to develop a robust capability to handle deepwater blowouts on the Outer Continental Shelf.
“To achieve our objective of safer offshore energy production, we must eliminate the gap between the technology and knowledge that allows oil and gas companies to tap reserves beneath 5,000 feet of water - and the technologies and strategies that allow us to deal with emergencies at those depths,” Salazar told a meeting of U.S. government, industry, and stakeholder leaders and experts.
“Secretary of Energy Steven Chu and I have convened this meeting to discuss the increased understanding we now have on how to strengthen blowout containment capabilities,” Salazar said. “It is my hope that today's discussion will help guide reforms that are raising the bar for the oil and gas industry's practices, as well as to help inform recommendations on whether and how to lift the current deepwater drilling suspension.”
Salazar noted that the Obama administration has executed the most aggressive offshore drilling reforms in the nation's history in response to the Deepwater Horizon blowout and spill. “Our goal,” the Secretary said, “is simple: to raise the bar on safety and environmental protections so that deepwater drilling can safely resume.”
In addition to Secretaries Salazar and Chu, the participants included Interior Deputy Secretary of the Interior David J. Hayes; Dr. Marcia McNutt, Director, United States Geological Survey; Dr. Tom Hunter, former Director, Sandia National Laboratory; Michael R. Bromwich, Director, Bureau of Ocean Energy Management, Regulation, and Enforcement; Ret.. Adm. Thad Allen, National Incident Commander; Rear Admiral Brian M. Salerno, Deputy Commandant for Operations, United States Coast Guard; Andrew Inglis, Chief Executive of Exploration & Production, BP; Rex W. Tillerson, Chairman& CEO, ExxonMobil; Hon. Don Winter, PhD, National Academy of Eningeering; and Elgie Holstein, Environmental Defense Fund.
