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 Announces Upcoming BLM Oil and Gas Lease Sales, Lauds Progress in Balanced Energy Agenda
Last edited 4/25/2016
WASHINGTON, D.C. – Secretary of the Interior Ken Salazar today described the progress the Department of the Interior has made in the last six months to responsibly develop oil and gas resources on public lands as part of President Obama's comprehensive energy strategy for the United States. Since January, the Department of the Interior has offered more than 2.5 million acres of U.S. public lands, primarily in the West, for oil and natural gas development and companies have leased 782,280 of those acres, paying more than $60 million in bonus bids and leasing fees.
“As part of President Obama's comprehensive energy strategy, our Bureau of Land Management has an active and robust program to responsibly develop onshore U.S. lands for traditional energy production,” Secretary of the Interior Ken Salazar said. “We have held 17 oil and gas lease sales since January and plan to hold another 20 sales in the next six months. Our nation needs a balanced approach to meet its energy needs today, continuing to rely on appropriate domestic sources of oil, gas and coal, while we accelerate the development of our vast renewable energy resources.”
So far this year, the Bureau has offered 2,261,854 acres in 1,749 parcels and sold oil and gas development leases on 782,280 of those acres in 866 parcels, collecting $60,108,904 in revenue.
For most federal oil and gas leases, 50 percent of the revenues collected are returned to the states where the oil and gas activity occurs. Of the remaining 50 percent of the revenues, 40 percent goes to a reclamation fund for water projects and 10 percent goes to the U.S. Treasury.
“The Bureau of Land Management plays an important role in working with industry and local communities that rely on traditional energy development on U.S. lands, and in ensuring the protection of wildlife and our treasured landscapes,” Salazar said.
The Bureau of Land Management held the following oil and gas lease sales this year: Montana on 1/27, 4/14 and 6/16; Wyoming on 2/3, 4/7 and 6/2; Utah on 3/24 and 6/23; Colorado on 2/12 and 5/14; Nevada on 3/10 and 6/9; New Mexico on 1/21 and 4/22; and one each in California, 3/11; Oregon, 3/12; and the Eastern States, 3/19.
The Bureau has scheduled an additional 20 oil and gas lease sales nationwide this year:
Eastern States on 6/25, 9/17 and 12/10; New Mexico, 7/22 and 10/21; Wyoming, 8/4, 10/2 and 12/1; Utah, 8/18 and 11/17; Montana, 8/25 and 11/3; Nevada, 9/8 and 12/8; California, 9/9 and 12/9; Oregon 9/10 and 12/10; and Colorado 9/17 and 11/12.
