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 of Agriculture, Interior and Homeland Security Announce Partnership to Develop Comprehensive Wildfire Management Strategy
Office of the Secretary

WASHINGTON, D.C. – Secretary of Agriculture Tom Vilsack, Secretary of the Interior Ken Salazar, and Secretary of Homeland Security Janet Napolitano today announced the formation of a federal partnership with state, regional, local and tribal leaders to develop a strategy to more effectively address America's wildland fire challenges.
At a meeting of the Wildland Fire Leadership Council in Washington, D.C., local officials joined governors, representatives of tribal governments and the departments of Agriculture, Interior, and Homeland Security to establish a blueprint for a “Cohesive Wildfire Management Strategy.”
“The Council provides the right framework for a strong national strategy to address the growing threats of wildfire,” said Secretary Salazar. “The Council's partnerships are key to the establishment of a national, intergovernmental wildfire policy that will ensure the safety of our firefighters and the citizens they protect as we confront longer and more intense fire seasons in more regions of the country.”
“There are no easy solutions to the challenges of wildland fire,” said Secretary Vilsack. “But a cohesive wildfire management strategy will provide the best blueprint to ensure community safety and the restoration of ecosystems that will, in the long run, benefit all Americans, especially those who live in rural areas.”
"Developing a comprehensive national strategy to prepare for and protect against wildfires that threaten the safety of Americans is an important part of our efforts to build a culture of resiliency in communities across the country,” said Secretary Napolitano.
At the Council meeting, federal, state, local and tribal government representatives agreed to develop a comprehensive landscape-scale analysis of all wildlands, based on the best available science, and a strategic blueprint of policy and program alternatives for the wildland fire community. The strategy will analyze three key components: landscape restoration, fire-adapted communities, and response to wildfire.
The Cohesive Wildfire Management Strategy will address America's increasing wildland fire challenges. Currently, millions of acres of public lands across the country are at risk of large wildfires due to overcrowded stands of trees, insect infestations, and invasions of non-native species. The group targets the completion of the strategy by this fall.
The Wildland Fire Leadership Council, re-established by a Memorandum of Understanding signed by Secretary Salazar, Secretary Vilsack and Secretary Napolitano on April 12 consists of federal, state, tribal, county and municipal government officials dedicated to the consistent implementation of wildland fire policies, goals and management activities.
