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.

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.
Interior, Agriculture Secretaries Announce New Purchases of Western Land Parcels with High Conservation Values
Last edited 4/25/2016
WASHINGTON, D.C. -- Secretary of the Interior Dirk Kempthorne and Secretary of Agriculture Ed Schafer announced today that four Federal land-management agencies are in the process of acquiring 12 pieces of property in seven Western states with $4.7 million from a special land conservation fund.
"The nearly $5 million to be used for these land purchases will bring into public ownership 1,587 acres that have extraordinary natural, scenic, recreational, or historical value," said Secretary Kempthorne. "Acquiring these parcels promotes conservation while helping to ensure effective public lands management."
"This unique joint effort enables the Federal land management agencies to work together in conserving magnificent landscapes for the benefit of the American people now and in the future," said Secretary Schafer. "With this tool, the best land and the best water are now part of our public treasures."
Of the 12 new properties to be purchased, Interior's Bureau of Land Management would acquire one 575-acre conservation easement within the Henrys Lake Area of Critical Environmental Concern in Idaho to protect lakefront property from rural residential subdivision. The U.S. Forest Service, National Park Service, and the U.S. Fish and Wildlife Service would acquire the other 11 properties, which encompass 1,012 acres.
The properties to be purchased by these three agencies are located within or next to Bridger-Teton National Forest (Wyoming), City of Rocks National Reserve (Idaho), John Day Fossil Beds National Monument (Oregon), Nestucca Bay National Wildlife Refuge (Oregon), Santa Fe National Forest (New Mexico), Shasta-Trinity National Forest (California), White River National Forest (Colorado), and Zion National Park (Utah).
The special land conservation fund used to purchase these properties was established by Congress under the Federal Land Transaction Facilitation Act of 2000, which authorizes the purchase of private "inholdings" from willing sellers in the Western states whose acreage is surrounded by or located next to certain lands under the management of the Bureau of Land Management, U.S. Forest Service, National Park Service, or the Fish and Wildlife Service.
The pending land purchases are funded from already completed Federal land sales. Under the Federal Land Transaction Facilitation Act, the Bureau of Land Management is authorized to sell fragmented or isolated parcels of public land that are difficult to manage, as well as lands that may have residential or commercial value, and then use the proceeds to support land-conservation purposes.
To date, a grand total of $49.4 million in funding under the Federal Land Transaction Facilitation Act has been approved for the acquisition of 24 parcels comprising 11,748 acres.
"The benefits of this sale-authority law are clear," said Kempthorne, who noted that the Federal Land Transaction Facilitation Act is set to expire in 2010.
The Bureau of Land Management, National Park Service, and the Fish and Wildlife Service are part of the U.S. Department of the Interior; the U.S. Forest Service is an agency of the U.S. Department of Agriculture.
