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 – Secretary of the Interior Ken Salazar will join youth from the Student Conservation Association, volunteers from Greater DC Cares, and Department of the Interior employees on Saturday, January 19, 2013, to work on beautification projects at the Martin Luther King, Jr., Memorial, as part of the National Day of Service.
Continuing a tradition the First Family began four years ago, Americans will kick off the 57th Presidential Inauguration weekend with a National Day of Service to honor the life and legacy of Dr. Martin Luther King Jr. Volunteers have organized events in all 50 states, and the Presidential Inaugural Committee is sponsoring a Service Summit on the National Mall with 100 organizations and seven service projects under one tent. The President and his team have always believed that our country is strongest when we all work together, when neighbors help neighbors, and communities find common goals.
