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.
Secretary Salazar's Statement Regarding the Moratorium on Deepwater Drilling

WASHINGTON, DC – Secretary of the Interior Ken Salazar issued the following statement regarding a decision today in U.S. District Court regarding the deepwater drilling moratorium:
“The decision to impose a moratorium on deepwater drilling was and is the right decision. The moratorium is needed to protect the communities and the environment of the Gulf Coast, and DOJ is therefore appealing today's court ruling.
“We see clear evidence every day, as oil spills from BP's well, of the need for a pause on deepwater drilling. That evidence mounts as BP continues to be unable to stop its blowout, notwithstanding the huge efforts and help from the federal scientific team and most major oil companies operating in the Gulf of Mexico. The evidence also continues to mount that industry needs to raise the bar on blowout prevention, containment, and response planning before deepwater drilling should continue.
“Based on this ever-growing evidence, I will issue a new order in the coming days that eliminates any doubt that a moratorium is needed, appropriate, and within our authorities.”
