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.

WASHINGTON, D.C. – David J. Hayes, one of the nation's foremost natural resource experts, was officially sworn in today as Deputy Secretary of the Department of the Interior, the second-highest-ranking official at the department. Secretary of the Interior Ken Salazar administered the swearing-in ceremony.
“This is a great and long-awaited day at the Department of the Interior,” Salazar said. “David Hayes brings a powerful combination of expertise and management experience dealing with complex natural resources and environmental challenges, including climate change policy,” Salazar said. “He has a strong record, thoughtful common sense approach and a steady management hand. He is a key part of our leadership team as we carry out President Obama's vision for our nation's economic and environmental recovery.”
President Obama nominated Hayes for the number two leadership position at Interior on February 27, 2009. The Senate confirmed him on May 20, at which time Secretary Salazar issued a statement that he welcomed the lifting of a hold on the nomination because “David is exceptionally qualified for this position and will bring intelligence, integrity and passion to the job.”
As Deputy Secretary, Hayes has the statutory responsibility as the Chief Operating Officer to help lead a Department of almost 70,000 employees and a budget of about $16 billion, including annual appropriations and permanent funding.
Hayes previously served as the Deputy Secretary of the Department of the Interior from 1999 to 2001, during which time he played a lead role in helping introduce modern water management approaches in the West, settling long-standing Indian water and land disputes, and establishing new national parks, including Great Sand Dunes National Park in Colorado.
Most recently, Hayes was a leader in President Obama's Transition Team, heading the agency review process for the Department of Energy, the Department of the Interior, the Department of Agriculture, and the Environmental Protection Agency.
Hayes was a partner at Latham & Watkins, where he earned distinction as one of the nation's top natural resource lawyers. In 2007 and 2008, he was a consulting professor at Stanford University's Woods Institute for the Environment, where he led a project to find achievable and practical climate change policy solutions.
Hayes graduated summa cum laude from Notre Dame in 1975, received his J.D. from Stanford in 1978, and was an editor of the Stanford Law Review. He currently serves as Chairman of the Board of Visitors for Stanford Law School. He and his wife, Elizabeth Haile Hayes, have three children, Katherine, Stephen, and Molly.
