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.
New Quarters to Feature National Parks and National Wildlife Refuges

WASHINGTON, DC -- Hot Springs, Yellowstone, Yosemite, and Grand Canyon National Parks will be the first sites commemorated in a new quarter-dollar program announced today by the U.S. Mint.
Starting in April of 2010, the America the Beautiful Quarters Program will begin producing quarters with reverse (tails side) designs showcasing a national park or other federally preserved area from each state, U.S. territory, and the District of Columbia.
“The new quarter program recognizes that public places of inspiration and recreation have always been important to Americans,” said Secretary of the Interior Ken Salazar. “The quarters highlight the diversity and magnificence of 48 National Park Service sites and two U.S. Fish and Wildlife Service refuges cared for by the Department of the Interior as well as six national forests administered by the Department of Agriculture. Hopefully the coins will encourage people to learn more about each area and its significance to our heritage.”
A new quarter will be introduced approximately every 10 weeks for eleven years. The 56 coins will be issued sequentially in the order in which the featured location was first placed under the care of the federal government.
The first, Hot Springs National Park, was established as Hot Springs Reservation in 1832 and later became a national park. Yellowstone National Park was established in 1872, followed by Yosemite in 1890 and the Grand Canyon in 1893.
Congress authorized the America's Beautiful National Parks Quarter Dollar Coin Act of 2008 to celebrate the nation's legacy of conservation. The legislation recalls noteworthy steps in the nation's preservation movement and quotes Theodore Roosevelt who said that nothing short of defending this country in wartime “compares in importance with the great central task of leaving this land even a better land for our descendents than it is for us.”
Salazar and the United States Mint selected the places based on recommendations from the governor or chief executive of each jurisdiction. Secretary of the Treasury Timothy F. Geithner approved the list on August 25, 2009.
In addition to the coins for circulation, the Mint will produce collectable items including proof sets, silver proof sets, a five ounce silver bullion coin, coin bags, and coin rolls for each quarter.
