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.
Secretary Jewell Lauds Enactment of Bipartisan Energy Legislation to Encourage Development of Small Hydropower, Support Rural Jobs
Office of the Secretary
WASHINGTON, D.C. — Secretary of the Interior Sally Jewell issued the following statement following President Obama's signature of two bills that are expected to create rural jobs and encourage the development of small hydropower projects, including within existing Bureau of Reclamation conduits, waterways and canals. The Hydropower Regulatory Efficiency Act and the Hydropower and Rural Jobs Act were signed into law today.
"I applaud the bipartisan efforts that will support the President's Climate Action Plan and our all-of-the-above energy strategy to boost domestic energy production, reduce our dependence on foreign oil and begin to slow the effects of climate change," Secretary Jewell said. "By streamlining the permitting of small hydropower on existing Bureau of Reclamation facilities, these laws will help expedite the development of renewable and affordable energy in the West and support the creation of rural jobs. There is more work to be done, but these efforts will help the Department of the Interior as we work to permit enough renewables on public lands to power more than 6 million homes."
The Hydropower and Rural Jobs Act provides greater certainty for the generation of clean, renewable hydroelectric power at those Reclamation sites through the regulatory process and administrative streamlining.
"The enactment of this legislation underscores our efforts to develop renewable energy on canal and conduit sites managed by Reclamation across the west," said Bureau of Reclamation Commissioner Michael L. Connor. "This unlocks the door to developing new sources of energy at hundreds of our facilities across the West while creating new jobs at the same time."
