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.

WASHINGTON, D.C. - Secretary of the Interior Ken Salazar lauded the upcoming PBS series on the national parks, The National Parks: America's Best Idea, at a premiere showing at the Capitol Visitor's Center Thursday evening, March 5.
He announced that director Ken Burns and co-producer Dayton Duncan were made honorary park rangers at the Department of the Interior earlier in the day after meeting with the Secretary.
“Their park series tells the story of a distinctly American idea,” said Salazar. “The parks belong to all Americans. For this reason, they not only chronicle our history, but are living symbols of democracy at work.”
The Secretary also indicated that the film series would help showcase the current needs and opportunities in our nation's parks.
“The Recovery Act that President Obama signed, and that we are working to swiftly and wisely implement, will allow us to invest $750 million in our national parks and get our economy moving again,” he said.
The event was hosted by WETA-TV, the National Parks Conservation Association, the National Park Foundation and the Public Broadcasting Service. The six-part series begins September, 2009 on PBS channels.
