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.
AMERICA'S GREAT OUTDOORS: Secretary Salazar, Director Abbey Visit Imperial Sand Dunes, Participate in Off-Highway Vehicle Recreation
Office of the Secretary

El CENTRO, Calif. -- Secretary of the Interior Ken Salazar and Bureau of Land Management Director Bob Abbey today visited the Imperial Sand Dunes Recreation Area and rode off-highway vehicles (OHV) in the California Desert to underscore President Obama's America's Great Outdoors, an initiative to promote and support partnerships with local communities to conserve open spaces and reconnect Americans to the outdoors.
“The Imperial Sand Dunes are a prime example of how partnerships can create world-class recreation opportunities, reinvigorate our approach to conservation and reconnect Americans, especially our young people, with the nation's recreation lands and waters,” Secretary Salazar said. “Thanks to folks like the American Sand Association, United Desert Gateway and a host of others, more than a million people flock to this unique desert landscape each year to enjoy responsible, family-based off-highway vehicle recreation, stunning scenery and wilderness solitude. Their visits infuse millions of dollars into the local economy and ensure a great family tradition for generations to come.”
“Covering 160,000 acres, the Dunes is a unique place that not only offers family recreation but also preserves wilderness and provides a home to rare desert plants and wildlife,” said BLM Director Abbey. “This magnificent dune system demonstrates how, in partnership with local communities, we can protect the health, heritage, resources, and social and economic value of our nation's lands.”
Secretary Salazar rode in a sand rail up one of the more challenging dunes and visited with three generations of off-highway vehicle enthusiasts as part of a tour highlighting President Obama's America's Great Outdoors initiative. Accompanied by Director Abbey, BLM's El Centro Field Manager Margaret Goodro and Dunes Manager Neil Hamada, the Secretary visited the OHV Safety Training operated by American Desert Foundation to meet some of the younger visitors and discuss the importance of safety measures.
The Secretary also talked with representatives of Imperial County staff to discuss the economic benefits and the commercial importance of the Dunes to surrounding communities. The Secretary ended the day at a campground where he met with families, some of whom have been visiting the dunes for generations.
Following President Obama's Feb. 16 report and memorandum establishing the America's Great Outdoors initiative, Secretary Salazar has been visiting with communities around the country to highlight the importance of working with the American people to develop a conservation and recreation agenda that makes sense for the 21st century.
Recognizing that many public and private lands and resources are under intense pressure, the President's report outlines ways in which the Federal Government will help empower local communities to accomplish their conservation and recreation priorities. These include:
Accessible parks or green spaces for our children.
A new generation of great urban parks and community green spaces.
Newly-restored river restorations and recreational “blueways” that power economic revitalization in communities.
Stronger support for farmers, ranchers, and private landowners that help protect rural landscapes and provide access for recreation.
The reinvestment of revenues from oil and gas extraction into the permanent protection of parks, open spaces, wildlife habitat, and access for recreational activities.
A 21st century conservation ethic that builds on local ideas and solutions for environmental stewardship and connecting to our historic, cultural, and natural heritage.
