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.
National Park Service Takes Next Step in Revitalization Project of Jefferson National Expansion Memorial
Office of the Secretary
WASHINGTON DC – Secretary of the Interior Ken Salazar today announced that the National Park Service (NPS) has initiated the next step in the proposed revitalization of the Jefferson National Expansion Memorial and remains on track to have the project completed in time for the 50th anniversary of completion of the Gateway Arch in 2015.
The NPS has opened a five week scoping period as part of the Environmental Assessment (EA). Members of the public are invited and encouraged to share their comments, concerns, or questions regarding the scope of the EA for proposed physical changes to the park and facilities as a result of the recent international design competition.
“The Jefferson National Expansion Memorial's revitalization can serve as a model of how great urban parks can provide opportunities for outdoor recreation and invite more people to fully enjoy our nation's natural beauty, culture and history,” Salazar said. “I encourage members of the public to engage in this design process as we seek to revitalize the park and strengthen its connections to both banks of the Mississippi River.”
The park's November 2009 General Management Plan directed the design competition as a means to revitalize Jefferson National Expansion Memorial by improving connections to the city and expanding programming, facilities, and partnerships, and to enhance the visitor experience. The winner, Michael VanValkenburg and Associates from New York, was selected by a jury from five finalists.
“The Gateway Arch symbolizes our nation's desire to move boldly toward the future,” National Park Service Director Jonathan B. Jarvis said. “Today's announcement is another step in that direction as we work to improve the park for the surrounding communities, for the nation, and for generations to come.”
The major components of the project currently under consideration include:
a landscaped “lid” over the depressed lanes of I-70 between the Gateway Arch grounds and downtown;
renovation of the underground museum and a new entrance;
accessibility improvements and new exhibits in the Old Courthouse;
development of accessible trails to the riverfront;
expanded visitor programming and amenities on the Gateway Arch grounds; and
improvements to the sustainability of the landscape at the park.
Secretary Salazar has made several visits to the park grounds as Secretary of the Interior, most recently in December, 2010 when he toured the park and reviewed the winning design concept. Salazar said that the project complements the goal of President Obama's America's Great Outdoors Initiative to establish great urban parks and expand opportunities for all Americans to enjoy outdoor recreation.
