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.

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.

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.
Salazar Joins Parkinson, Brownback, Sebelius to Break Ground for Visitor Center at Tallgrass Prairie National Preserve

STRONG CITY, KS -- Secretary of the Interior Ken Salazar today joined Kansas Governor Mark Parkinson, Senator Sam Brownback, and Secretary of Health and Human Services Kathleen Sebelius to break ground on a new visitor center and administrative buildings at Tallgrass Prairie National Preserve.
“This new visitor center will help conserve and educate Americans about the tallgrass prarie and America's Great Outdoors while creating good jobs here in Kansas,” Secretary Salazar said. “The facility will open a window to the expansive rolling hills and wide-open vistas that once covered 140 million acres of North America.”
The project is the result of a partnership including the federal government, the State of Kansas, the Kansas Department of Transportation, The Nature Conservatory, and the Kansas Park Trust. The National Park Service and the Kansas Department of Transportation will equally share the cost of the $6 million project, which will be completed in early 2012. Salazar also thanked the National Park Trust for donating the historic buildings and land in 2002 needed for developing the visitor center and related facilities.
Salazar noted that partnerships such as the one at the preserve are at the heart of President Obama's America's Great Outdoors initiative to create a new conservation ethic for the 21st century and reconnect Americans to the great outdoors.
“We want to support what so many Americans are already doing in their communities to conserve our land and its resources and to get people, especially young people, outdoors to enjoy them,” Salazar said. “We want to tap into the power of partnership so evident here at the Tallgrass Prairie National Preserve.”
The Tallgrass Prairie National Preserve was established in 1996 to protect a nationally significant remnant of the once vast tallgrass prairie and its cultural resources. Tallgrass prairie once covered 140 million acres of North America. Within a generation the vast majority was developed and plowed under. Today less than 4% remains, mostly in the Kansas Flint Hills.
