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.

Secretary of the Interior Ken Salazar joined Oregon Governor Ted Kulongoski, California Governor Arnold Schwarzenegger, PacificCorp Chief Executive Officer Greg Abel and the chairmen of the Klamath, Yurok and Karuk Tribes in the Oregon Capitol Rotunda to announce final agreements that could potentially lead to removal of four dams on the Klamath River and the largest river restoration project in our nation's history. The potential removal of the dams is a key piece of a major restoration effort for the Klamath developed by more than 30 diverse stakeholders, including California and Oregon, three tribes, PacifiCorp, water users and conservation groups.
