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 Salazar to Offer a New Round of Oil Shale Research, Development and Demonstration Leases
Last edited 4/25/2016
WASHINGTON, D.C. – The Department of the Interior will offer a second round of research, development, and demonstration leases for oil shale in Colorado and Utah and withdraw the previous administration's proposal for expanded RD&D leases, Secretary of the Interior Ken Salazar announced today.
“We need to push forward aggressively with research, development and demonstration of oil shale technologies to see if we can find a safe and economically viable way to unlock these resources on a commercial scale. The research, development, and demonstration leases we will offer can help answer critical questions about oil shale, including about the viability of emerging technologies on a commercial scale, how much water and power would be required, and what impact commercial development would have on land, water, wildlife, and communities.”
The Department has submitted a notice that will appear in the Federal Register on Friday, Feb. 27, 2009 that will ask industry, local communities, states, and stakeholders for their advice on what the terms and conditions of the second round of RD&D leases should be. That comment period will be open for 90 days.
“Following that, the Department will move ahead with a solicitation for RD&D leases, based on sound policy and public input,” Salazar said. “This will help us restore order to a process that, under the previous Administration, was turned upside down. We look forward to hearing from the public, industry, and local communities as we move toward offering a second round of research, development, and demonstration leases.”
Salazar said he was withdrawing the previous Administration's solicitation on RD&D leases because it included several flaws, including locking in low royalty rates that would shortchange taxpayers. “The previous Administration offered their RD&D oil shale leases just days before leaving office, made the parcels four times the size of the current six RD&D leases, and then locked in low royalty rates and a premature regulatory framework for those leases,” the Secretary said. “If oil shale technology proves to be viable on a commercial scale, taxpayers should get a fair rate of return from their resource.”
As a U.S. Senator, Salazar helped author the provision in the 2005 Energy Policy Act that created the current RD&D leasing program, under which Interior's Bureau of Land Management offered six 160 acre parcels for companies to do research and development of oil shale technologies.
