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 Announces Approval of Major Wind Energy Project on Public Lands in Arizona
Office of the Secretary
Announcement Follows Release of President Obama's Plan to Cut Carbon Pollution, Grow American-Made Energy
WASHINGTON, D.C. – As part of President Obama's comprehensive plan to reduce carbon pollution, move our economy toward American-made clean energy sources and begin to slow the effects of climate change, Secretary of the Interior Sally Jewell today announced the approval of a major wind energy project in Arizona that, when built, will provide up to 500 megawatts to the electricity grid -- enough energy to power up to 175,000 houses – and create approximately 750 jobs through construction and operations. As part of President Obama's comprehensive climate action plan, he challenged the U.S. Department of the Interior to approve an additional 10,000 above the original goal of 10,000 megawatts of renewable energy production on public lands by 2020.
The project, proposed by BP Wind Energy North America, Inc., would erect up to 243 wind turbines on Federal lands for the Mohave County Wind Farm, which would be located in northwestern Arizona about 40 miles northwest of Kingman.
“These are exactly the kind of responsible steps that we need to take to expand homegrown, clean energy on our public lands and cut carbon pollution that affects public health,” said Secretary Jewell. “This wind energy project shows that reducing our carbon pollution can also generate jobs and cut our reliance on foreign oil.”
With today's announcement, Interior has approved 46 wind, solar and geothermal utility-scale projects on public lands since 2009, including associated transmission corridors and infrastructure to connect to established power grids. When built, these projects could provide enough electricity to power more than 4.4 million homes and support over 17,000 construction and operations jobs.
Interior's Bureau of Land Management (BLM) has identified an additional 14 active renewable energy proposals slated for review this year and next. The BLM identified these projects through a process that emphasizes early consultation and collaboration with its sister agencies at Interior – the Bureau of Indian Affairs, the U.S. Fish and Wildlife Service, and the National Park Service – demonstrating President Obama's and Interior's ongoing commitment to “smart from the start” planning.
Today's decision paves the way for right-of-way grants for use of approximately 35,000 acres of BLM land and 2,800 acres of Bureau of Reclamation land. The company agreed to undertake significant mitigation efforts to minimize impacts to wildlife and other resources, including reducing the project's footprint by about 20 percent from the original proposal. The smaller footprint will protect golden eagle habitat and reduce visual and noise impacts to the Lake Mead National Recreational Area. In particular, today's decision bars the installation of turbines within designated sensitive areas to avoid golden eagle nesting locations, as well as provides for a 1.2-mile buffer zone to protect the nests. Additionally, no turbine will be closer than a quarter-mile to private property.
“The project reflects exemplary cooperation between our BLM and Bureau of Reclamation and other Federal, state and local agencies, enabling a thorough environmental review and robust mitigation provisions,” said BLM Principal Deputy Director Neil Kornze. “This decision represents a responsible balance between the need for renewable energy and our mandate to protect the public's natural resources.”
“I added my signature of approval for this vital project on the same week that President Obama challenged Interior to intensify its development of clean, renewable energy,” Bureau of Reclamation Commissioner Michael L. Connor said. “Reclamation's hydropower resources are a centerpiece of the nation's renewable energy strategy. We are pleased to also play a significant role in this important wind energy project.”
