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.
Every day someone like you becomes a wildland wildfire fighter, a teacher, a trail-builder, a museum curator, or a park ranger. Discover your opportunities in national parks. Come to play. 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.

WASHINGTON, DC — In a continuing effort to improve transparency and openness at the Department of the Interior, Secretary Salazar announced that he is launching four new web tools that will help Americans connect with the nation's heritage, natural resources, and cultures.
The public will now be able to follow the work of the Department of the Interior and its agencies on YouTube, Facebook, Flickr, and Twitter. Secretary Salazar has also begun sending emails directly to all of the Department's 67,000 employees with updates on important initiatives and has opened a suggestion box to which Interior employees can submit ideas and feedback to the Secretary and senior management.
“For years, the Department has trailed far behind other federal agencies in the world of technology,” said Secretary of the Interior Ken Salazar. “Now, with the New Media tools at our disposal, we can not only improve transparency at the Department of the Interior, but better share with the American public information about the natural, cultural, and historic resources of which we are stewards. I am also pleased that at long last I am able to send e-mail messages directly to employees and hear back from them through our new suggestion box. This is an exciting new era of New Media at the Department of the Interior.”
The following list shows what the Department will be launching.
Ken Salazar has joined his counterparts Secretary of Energy Steven Chu and EPA Administrator Lisa Jackson on Facebook. The Secretary's Facebook page can be found at http://Facebook.com/SecretarySalazar.
The Department of the Interior launched a Flickr page at: http://www.flickr.com/photos/USInterior. Currently, DOI is using Flickr to post photos from the Secretary's events and active travel schedule. Future plans include posting historic photos from across the Department using Flickr Commons to provide greater access to our vast collections of historic and scientific photos.
The latest news, updates and happenings at the Department of Interior will now be accessible via Twitter. (http://www.Twitter.com/USInteriorNews). Several other bureaus with Interior have also launched active Twitter accounts including the National Park Service (http://twitter.com/NatlParkService) and the U.S. Geological Survey (http://twitter.com/USGS). The U.S. Geological Survey is also using Recovery Funds to fund a graduate student project that will track responses to earthquakes via Twitter. In this exploratory effort, the USGS is developing a system that gathers real-time, earthquake-related messages from the social networking site Twitter and applies place, time, and quantity data to provide geo-located earthquake detection within 60 seconds of an event's origin time. This approach also provides a central directory of short first-impression narratives and, potentially, photos from people at the hazard's location.
