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.
AMERICA'S GREAT OUTDOORS: Salazar Announces Establishment of Everglades Headwaters NWR and Conservation Area
Exemplifies Administration's Successful Approach to Working Landscape Conservation
KISSIMMEE, Fla. – As part of President Obama's America's Great Outdoors initiative, Secretary of the Interior Ken Salazar today accepted the first donation of land in south-central Florida to officially establish the Everglades Headwaters National Wildlife Refuge and Conservation Area – conserving one of the last remaining grassland and longleaf pine savanna landscapes in eastern North America.
The new refuge and conservation area – the 556th unit of the National Wildlife Refuge System – is being established with the support of local ranchers, farmers and landowners who are working cooperatively with Interior and the U.S. Fish and Wildlife Service to conserve the wildlife values on their lands while retaining their right to raise livestock or crops, an approach championed by the Obama administration.
If fully realized, the refuge and conservation area will span 150,000 acres north of Lake Okeechobee. Two-thirds of the acreage, or 100,000 acres, will be protected through conservation easements purchased from willing sellers. With easements, private landowners retain ownership of their land, as well as the ability to continue farming or ranching the land. The easements would ensure the land could not be subdivided or developed.
“This is an outstanding example of the 21st century approach to conservation envisioned by President Obama when he unveiled his America's Great Outdoors initiative last year,” Salazar said. “Working in close partnership with landowners, we are taking a major step to safeguard the long-term health of the Everglades in the Kissimmee Valley, while ensuring the area's ranching and farming heritage and economy remain strong. Just as we have done in Kansas, Montana and the Dakotas, our locally-driven, cooperative approach to conserving the Everglades Headwaters will help grow a robust outdoor recreation economy for central Florida, while preserving ranchers' rights to live off the land.”
The U.S. Fish and Wildlife Service (Service), which manages the National Wildlife Refuge System, is working closely with ranchers and other private landowners, the Florida Fish and Wildlife Conservation Commission and other state agencies, conservation organizations, users' groups, Native American tribes and federal agencies in the creation of the new refuge and conservation area.
“We are inspired by the excellent conservation opportunities that exist here as a result of the efforts of our ranching community to protect working lands across generations," said Service Director Dan Ashe. “The extraordinary vision of our many partners will help protect significant wildlife species while supporting a way of life that is vital to our citizens. This effort will restore wetlands in the headwaters area, preserve working ranches, and support a healthy environment for central and south Florida, as well as increase opportunities to hunt, fish, hike, bird watch, and learn about the importance of this landscape.”
The establishment of the new refuge and conservation area is one of a series of conservation projects under the Obama administration to work locally with landowners, conservation stakeholders, and state, tribal and local governments to conserve vital habitat on working landscapes. These include:
The million-acre Flint Hills Legacy Conservation Area in Kansas – the first new unit of the National Wildlife Refuge System authorized under the Obama administration, which will help maintain the integrity of tallgrass prairie wildlife habitat, stream water quality and the agricultural heritage of the Flint Hills;
The Dakota Grassland Conservation Area, which was approved in September 2011, will conserve prairie landscapes, wildlife resources and working lands in the Prairie Pothole Region, an area that supports more than half of the nation's migratory waterfowl; and
The successful community-based conservation initiatives taking place in the Crown of the Continent, a vast and intact landscape that includes portions of northwestern Montana as well as British Columbia and Alberta.
The Everglades, which receives water from the Kissimmee River Valley, will benefit from the conservation and restoration of its headwaters through enhanced water quality, quantity and storage.
The U.S. Fish and Wildlife Service held six public meetings in 2011 to gather input on the proposal; collected written comments; and met with representatives of local, state and federal agencies, as well as Native American tribes.
Salazar announced the Service's intent to evaluate this area in January 2011 and proposed to establish the new refuge and conservation area last September. During 2011, the Service received more than 40,000 comments on the proposal, the overwhelming majority of which expressed support.
