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, D.C.—On Tuesday, Jan. 17, Secretary of the Interior Ken Salazar and U.S. Fish & Wildlife Service Director Dan Ashe will kick-off a two day trip to Florida to make two important conservation announcements that are part of the Administration's efforts to preserve and restore the Florida Everglades. The visit comes as part of President Obama's America's Great Outdoors (AGO) initiative to establish a community-based, 21st century agenda for conservation, recreation, and reconnecting Americans to the outdoors.
During next week's trip, Secretary Salazar will highlight the job-creating impacts and economic benefits of tourism, outdoor recreation and conservation in the Everglades and around Florida.
On Tuesday, Salazar and Ashe will join U.S. Senator Bill Nelson to make an announcement regarding wildlife and the Florida Everglades. The announcement will take place along the Tamiami Trail just outside of Miami. Later on, Salazar will attend the Everglades Foundation “Everglades Water Supply Summit” in Tallahassee where he will identify next steps in the restoration of the Florida Everglades during a panel discussion entitled, “What's Next.”
On Wednesday, Salazar and Ashe will conclude their trip in Haines City with Senator Nelson where they will make an important announcement regarding the proposed Everglades Headwaters National Wildlife Refuge and Conservation Area.
