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.

CORTEZ, Colo. – On Saturday, September 22, 2012, Secretary of the Interior Ken Salazar will travel to Mesa Verde National Park in Colorado where he will meet with local stakeholders to discuss how travel, tourism and outdoor recreation can serve as economic engines for local communities. Following the meeting, Salazar will tour construction underway for the park's new research and visitor center, to be completed by the end of December.
In 2010, Mesa Verde National Park hosted more than 560,000 visitors who spent $41 million and supported 560 jobs in the local economy.
Salazar is co-chair of President Obama's Travel and Tourism Task Force, working to expand travel to and within the U.S. On Wednesday, the U.S. Department of Commerce announced that the travel and tourism industry is on pace for record exports in 2012. International visitors spent an estimated $13.7 billion on travel to, and tourism-related activities within, the United States during the month of July alone--$350 million (3 percent) more than was spent in July 2011.
The park's new visitor center will house Mesa Verde's three million artifacts and world-class archives. The facility will also feature a bookstore, visitor information desk, exhibits and trip planning materials.
Following the Mesa Verde visit, Salazar will meet with the Ute Mountain Ute Tribe and the Southern Ute Indian Tribe to discuss Interior's ongoing commitment to empowering Indian nations.
