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.

SAN DIEGO, CA – On Wednesday, August 13, Secretary of the Interior Sally Jewell will join U.S. Fish and Wildlife Service Director Dan Ashe and state and local officials to make an exciting announcement regarding the San Diego National Wildlife Complex in Southern California. The event will focus on reaching new audiences and engaging Southern California's urban communities and youth in conservation and outdoor recreation.
The San Diego Complex includes the San Diego Bay, San Diego, Seal Beach and Tijuana Slough NWRs, protecting over 16,000 acres of a rich diversity of native species and their habitats in the midst of a highly urbanized coastal environment.
Last October, the Department launched an ambitious youth initiative to inspire millions of veterans and young people to play, learn, serve and work outdoors. President Obama strongly supported the initiative by proposing $50.6 million for Interior youth programs in his 2015 budget.
