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.
Salazar Highlights Fast-Track Renewable Energy Projects
Last edited 4/25/2016
WASHINGTON, D.C. -- Citing what he called America's urgent need for a diverse energy supply, Secretary of the Interior Ken Salazar today detailed several renewable energy projects that are on a fast track, including a 400-megawatt solar tower development available for public review and five others that are poised to begin environmental impact studies. Five of these are solar projects and one is a wind farm; all are located in California.
“Under President Obama's leadership, we have entered a new energy frontier," Salazar said. “By putting these renewable energy projects on a fast track, we are managing our public lands not just for conventional energy development but also for environmentally responsible renewable energy production that will power our clean energy future.”
Interior's Bureau of Land Management (BLM) and the California Energy Commission have completed a joint draft Environmental Impact Statement for the BrightSource solar project in the Ivanpah Valley near Interstate 15 in San Bernardino County. The draft EIS is ready for public review and will be published in the Federal Register next week. This project, which will deploy solar power tower technology on about 4,000 acres of land, will have the capacity to generate 400 megawatts of electricity.
The other five fast-track projects noted by Secretary Salazar are:
Solar Millennium (Palen)
Solar Millennium (Blythe)
Solar Millennium (Ridgecrest)
NextEra Genesis (Ford Dry Lake)
AES (Daggett Ridge)
Each of these projects will be fully or partly sited on public lands managed by the BLM, which has identified nearly 23 million acres of public land with solar energy potential in six southwestern states and more than 20 million acres of public land with wind energy potential in 11 western states. “Moving forward with these projects is a tangible sign that our nation is poised to enter its green energy future,” said BLM Director Bob Abbey.
Fast-track projects are those where the companies involved have demonstrated to BLM that they have made sufficient progress to formally start the environmental review and public participation process. These projects are advanced enough in the permitting process that they could potentially be cleared for approval by December 2010, thus making them eligible for economic stimulus funding under the American Recovery and Reinvestment Act of 2009. All renewable energy projects proposed for BLM-managed lands receive full environmental reviews required by the National Environmental Protection Act. A number of other renewable energy projects also are on fast-track status and could soon be ready for environmental study and public review.
The draft environmental impact statement for the BrightSource solar energy development concluded the project could proceed without harming federally and state protected plants and wildlife under certain conditions. Among those, the statement recommends that the developer be required to purchase and manage up to 12,000 acres of habitat for the desert tortoise because the project would remove about 4,000 acres of habitat used by the protected species.
The solar-thermal power plant proposed by BrightSource Energy Inc. would serve utilities owned by PG&E Corp. (PCG) and Edison International (EIX). The facility would help meet California's goals of reducing greenhouse gas emissions and producing 33 percent of its electricity from renewable resources by 2020.
