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.

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.
AMERICA'S GREAT OUTDOORS: Secretary Salazar Announces $47 million in Historic Preservation Grants to States
WASHINGTON -- Secretary of the Interior Ken Salazar today announced $46.9 million in historic preservation grants to the 50 States, the District of Columbia, the U.S. Territories, and three affiliated Pacific island states. The grants will enable the states to preserve and protect our nation's historic sites without expending tax dollars.
“National Preservation Grants invest revenue from oil and gas development into telling the story of America by enabling the people of each state and territory the opportunity to preserve the places that are unique to their heritage,” Secretary Salazar said. “These grants leverage private investments in historic preservation activities and help spur tourism, create jobs, and build pride in communities across the nation.”
The Historic Preservation Fund is supported by revenue from federal oil leases on the Outer Continental Shelf. The National Park Service administers the fund and uses the majority of appropriated funds to distribute matching grants to State and Tribal Historic Preservation Officers.
“Throughout the country, historic preservation fund grants and other federal historic preservation programs help sustain and revitalize communities,” Director of the National Park Service Jonathan B. Jarvis said. “Historic preservation promotes heritage tourism and can transform under-utilized and often-vacant historic buildings into revenue-generators for local economies. The National Park Service is honored to be invited into so many communities and is proud to assist in saving and sharing history.”
States officials use the grants to fund preservation projects, such as survey and inventory, National Register nominations, preservation education, architectural planning, historic structure reports, community preservation plans, and bricks-and-mortar repair to buildings.
