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.
Agriculture Secretary Tom Vilsack and Interior Secretary Sally Jewell to Host Media Conference Call on the 2013 Wildfire Season Forecast

WASHINGTON – On Monday, May 13, Agriculture Secretary Tom Vilsack and Interior Secretary Sally Jewell will host a media conference call to provide an outlook for the 2013 fire season and to outline the federal government's efforts to ensure collaboration in protecting Americans from wildfire. They will be joined by U.S. Fire Administrator Ernest Mitchell from FEMA's U.S Fire Administration and John Segar, Chairman of the National Multi-Agency Coordinating Group at the National Interagency Fire Center.
This year, significant fire potential is predicted to be above normal in much of the West, including almost all of Arizona, New Mexico, California and Oregon; and portions of Montana, Idaho, Colorado, Utah, and Washington. In 2012, 9.3 million acres of private, state, and federal land, and more than 4,400 structures burned in wildfires. That was the third highest number of acres burned since at least 1960, the earliest date with reliable records.
