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.

WASHINGTON, D.C. -- Secretary of the Interior Ken Salazar, Deputy Secretary David J. Hayes and other senior officials from the Interior Department and Commerce Departments today met with California Natural Resources Secretary Lester Snow, county officials and diverse California water interests about the proposed long-term Bay Delta Conservation Plan.
The meeting at the Department of the Interior's Stewart Udall Building in Washington, D.C., included representatives of urban and agricultural water districts, conservation groups, and fishermen.
“The status quo in the Bay Delta is unsustainable and unacceptable to everyone,” Secretary Salazar said. “We need to forge forward-thinking solutions that will improve the reliability of water deliveries and restore the Bay Delta ecosystem.”
“The Bay Delta Conservation Plan must be based on science and the input of all parties and the public,” said Deputy Secretary Hayes. “We appreciate the continuing work and dedication of the stakeholders who are moving this process forward and who are so committed to the future of California's economy, water supplies, and environment.”
