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.
Arkansas Senator Mark Pryor Appointed to Migratory Bird Conservation Commission
Office of the Secretary

WASHINGTON, D.C. — Secretary of the Interior Ken Salazar today announced that Senator Mark Pryor has been appointed to the Migratory Bird Conservation Commission. The Commission, which is chaired by Secretary Salazar and includes members of Congress and cabinet secretaries, reviews and approves the purchase of wetlands and other areas of vital wildlife habitat for inclusion in the National Wildlife Refuge System.
“Senator Pryor will be a tremendous asset to the Migratory Bird Conservation Commission,” said Salazar. “His leadership and support for conservation throughout his home state of Arkansas is evident, and he will play a major role in helping the Commission preserve America's great outdoors.”
In addition to voting on land acquisition projects for migratory bird habitat at National Wildlife Refuges, the Commission also approves project funding under the North American Wetlands Conservation Act (NAWCA). NAWCA provides Federal funding for public-private partnership projects that protect, enhance, restore, and manage wetlands and other associated habitats across North America.
“I am pleased and honored to join the Migratory Bird Conservation Commission,” said Pryor. “Arkansas' natural resources are a defining feature of our state, and preserving these habitats is important to wildlife, hunters, and the surrounding communities. I look forward to working with the bipartisan members of the Commission and ensuring Arkansas interests are well represented.”
The Commission usually convenes three times per year during the months of March, June, and September, or as needed to approve land acquisitions and easement purchases, NAWCA projects. Since the Commission's establishment, more than six million acres have been acquired by the U.S. Fish and Wildlife Service for addition to the National Wildlife Refuge System. The Service administers the Commission on behalf of the Secretary.
Land projects that come before the Commission for consideration are funded from the Migratory Bird Conservation Fund. There are two major sources of money for the Fund. The most well-known source is the revenue received from the sale of Migratory Bird Hunting and Conservation Stamps, commonly known as Duck Stamps. The other major source is import duties collected on arms and ammunition In addition to Sen. Pryor, Commission members include:
Chairman - Ken Salazar, Secretary of the Interior
Thad Cochran, Senator from Mississippi
John D. Dingell, Congressman from Michigan
Robert J. Wittman, Congressman from Virginia
Tom Vilsack, Secretary of Agriculture
Lisa Jackson, Administrator, Environmental Protection Agency
Secretary - A. Eric Alvarez, Chief, Division of Realty, Fish and Wildlife Service
