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 - At the direction of the President, Department of the Interior Secretary Ken Salazar, Environmental Protection Agency Administrator Lisa Jackson and NOAA Administrator Jane Lubchenco will return to the Gulf region next week as they continue their work, aggressively responding to the BP oil spill.
These officials' actions on scene will be coordinated by National Incident Commander Admiral Thad Allen, who is leading the administration-wide response and directing all interagency activities.
Administrator Jackson will make her fourth trip to the Gulf Coast to inspect coastline protection and cleanup activities and meet with community members to discuss ongoing efforts to mitigate the oil's impacts on public health and the environment. A native of the Gulf region, Administrator Jackson will spend a total of six days on the ground, visiting Louisiana, Mississippi and Alabama to review plans for cleanup of oil-impacted wetlands and marshes, analyze scientific monitoring of dispersant use, and ensure that recovery and cleanup plans are proceeding quickly.
Secretary Salazar will make his eighth trip to the area to meet with top BP officials, federal personnel and government scientists in Houston to get a firsthand account of the on-scene direction and oversight of BP's efforts to cap the leaking well. He will also participate in discussions with state, local and business leaders to discuss the ways the administration is supporting their communities during this catastrophe.
Administrator Lubchenco will make her third visit to the affected area to meet with top government and independent scientists and engineers who are working with BP and coordinating efforts across the federal government to ensure the best science is used to assess and mitigate the BP oil spill's impacts to the environment.
President Obama visited the affected area for the second time yesterday to view the administration's all-hands-on-deck response to this unprecedented disaster. He spoke to the frustration felt by those in the local community and across America and discussed extensively what he saw touring the tragedy this morning. The President also commended those in the area who have “rolled up their sleeves” to help with the clean up, saying that “we're in this together.”
In total, senior administration officials have visited the region 28 times since BP's oil rig exploded on April 20—including trips by the President, National Incident Commander Admiral Thad Allen, Interior Secretary Salazar, EPA Administrator Jackson, Homeland Security Secretary Janet Napolitano, Energy Secretary Steven Chu, Commerce Secretary Gary Locke, Chairman of the Joint Chiefs of Staff Admiral Mike Mullen, NOAA Administrator Lubchenco and SBA Administrator Karen Mills.
