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.
Public shares ideas, concerns at America's Great Outdoor Initiative listening session
Office of the Secretary

Godfrey, Ill. — Secretary of the Interior Ken Salazar today hosted a listening session under President Obama's America's Great Outdoors initiative to hear from individuals on how to better conserve our nation's land, water and wildlife and develop opportunities for Americans to enjoy outdoor recreation. Prior to the America's Great Outdoors listening session, Secretary Salazar joined Senator Claire McCaskill at the Jefferson National Expansion Memorial where they celebrated the 100th anniversary of the Gateway Arch designer Eero Saarinen and viewed the designs of five finalists participating in an International Design Competition to reinvigorate the Memorial and St. Louis Arch Grounds.
The listening session, one of a series taking place across the country, gave people an opportunity to share how communities are meeting the challenges of modern-day land conservation and reconnecting Americans to the outdoors. Secretary Salazar was joined by Jo-Ellen Darcy, Assistant Secretary of the Army for Civil Works.
Preservation and conservation served as the foundation for discussion at the public listening session, which drew a crowd of more than 400 from the Alton, Ill., and St. Louis Metro areas. Salazar said it is precisely such discussion that will help meet the intent of the Initiative.
“From the banks of the Mississippi River to the nation's iconic Gateway Arch, this region is home to many special and historic treasures,” said Salazar. “We continue to build momentum with each America's Great Outdoors session and it is because of the passion and commitment we all share in protecting the places we love. Thank you for joining a conversation that will help shape a conservation agenda for generations to come.”
“Today's listening session, located near the confluence of the Illinois and Missouri Rivers with the Mississippi, brought to light the importance of conserving the nation's water resources and connecting with the environment,” Darcy said. “The people living here are true environmental stewards and have a passion for our American outdoors. Their drive and commitment to the outdoors will serve as a foundation for the 21st century conservation agenda.”
Prior to the public listening session, Darcy met with more than 200 youth at the National Great Rivers Museum in Alton, Ill, to hear their ideas on conserving and connecting with the outdoors. Darcy and the youth participated in a number of hands-on activities regarding water conservation and recreation.
“Working with the children brings the importance of the America's Great Outdoors initiative to the forefront,” Darcy said. “Even at a young age, these children understand the need to preserve and protect our outdoor spaces.”
President Obama inaugurated the America's Great Outdoors Initiative at the White House Conference on the Great Outdoors in April. The conference brought together leaders from communities across the country that are working to protect their outdoor spaces and focused on developing and supporting innovative ideas for improving conservation and recreation at the local level.
In a presidential memorandum, he called on the Secretaries of the Interior and of Agriculture, the Administrator of the Environmental Protection Agency, and the Chair of the Council on Environmental Quality to lead the initiative, in coordination with the departments of Defense, Commerce, Housing and Urban Development, Health and Human Services, Labor, Transportation, Education, and the Office of Management and Budget.
