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.

PELICAN ISLAND, FL. – On Friday, January 11, Secretary of the Interior Ken Salazar will travel to Florida to celebrate the establishment of six new national wildlife refuge units across the country during the past year and the renaming of a seventh in honor of a late U.S. Fish and Wildlife Service director by laying commemorative planks on a walkway at Pelican Island National Wildlife Refuge in Florida. Salazar will also discuss the economic importance of tourism and conservation with the Miami Chamber of Commerce and give the keynote address at the Everglades Coalition annual conference.
The six new refuge units to be honored are: Valle de Oro National Wildlife Refuge in Albuquerque, NM; Rio Mora National Wildlife Refuge and Conservation Area near Mora, N.M., Hackmatack National Wildlife Refuge in southeastern Wisconsin and northeastern Illinois; Sangre de Cristo Conservation Area in Colorado; Swan Valley Conservation Area in Montana; and Everglades Headwaters National Wildlife Refuge in Florida.
