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.

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, Ashe Announce Historic Conservation Easement in Sangre de Cristo Mountains
90,000 acres to be part of proposed Sangre de Cristo Conservation Area
FORT GARLAND, Colo. – Secretary of Interior Ken Salazar and U.S. Fish and Wildlife Service Director Dan Ashe today announced that noted conservationist Louis Bacon intends to donate a conservation easement totaling approximately 90,000 acres in the Sangre de Cristo Mountains bordering the San Luis Valley. This easement will provide the foundation for the proposed new Sangre de Cristo Conservation Area, which the Service is in the process of establishing.
“This is the largest single conservation easement ever donated to the U.S. Fish and Wildlife Service and it happens to be in one of the most beautiful places in the country, the Sangre de Cristo Mountains and the San Luis Valley,” Salazar said. “Thanks to Louis Bacon's deep commitment to conservation, we will now be able to preserve a diverse mosaic of public and private lands, creating a landscape corridor for fish and wildlife unlike any place in America.”
Bacon, a longtime advocate and proponent of landscape and wildlife conservation, owns the Blanca and Trinchera Ranches located in the San Luis Valley and intends to donate the conservation easement announced today on the Blanca. The Trinchera Ranch is currently protected by an easement administered by Colorado Open Lands.
“I have worked on a number of conservation and preservation projects in the United States and overseas, but nothing with the scope and importance of my efforts on Trinchera Ranch, in the breathtaking Sangre de Cristo Mountain Range,” said Louis Bacon. “That is why I am proud to announce that, should Interior choose to go forward with the Sangre de Cristo Conservation Area effort, I will place approximately 90,000 currently unprotected acres of the Blanca portion of Trinchera Ranch into a conservation easement with the United States Fish and Wildlife Service and, thus, protecting all 172,000 acres of the Ranch.”
Bacon continued, “This action will protect the Blanca Ranch in perpetuity and create a key connection in the large, diverse system of protected lands here along the Sangre de Cristo range and in the San Luis Valley. As I make this commitment, I want to thank Secretary Salazar, the United States Fish & Wildlife Service and Department of Interior staff for their commitment to conservation here in Colorado and across the nation – we are well served by their leadership and forethought.”
The diverse iconic landscapes of these ranches feature breathtaking vistas of high desert shrubs and mountain grasslands, combined with alpine forest and alpine tundra. The area stretches up to the top of one of the highest peaks in Colorado, Blanca Peak at 14,345 feet above sea level. It falls in the center of the Sangre de Cristo mountain range, the longest mountain chain in the United States, and borders the Great Sand Dunes National Park and Preserve.
Under President Obama's America's Great Outdoors initiative to establish a 21st century conservation agenda, Interior has spearheaded a series of voluntary partnerships with landowners to conserve rural landscapes while ensuring ranching, farming and other traditional ways of life remain strong. These initiatives include new units of the National Wildlife Refuge system, such as the Flint Hills Legacy Conservation Area in Kansas, the Dakota Grassland Conservation Area of South Dakota and North Dakota, and the Rocky Mountain Front Conservation Area in Montana.
The Fish and Wildlife Service has been working with landowners in the San Luis Valley on a similar locally-led, voluntary, cooperative partnership effort to conserve wildlife habitat and keep working lands working. As with any conservation area, the Service only acquires conservation easements from willing sellers.
“This unprecedented land donation will lay the foundation for the creation of the Sangre de Cristo Conservation Area in connection with the Service's San Luis Valley Land Protection Plan,” Ashe said. “As part of the America's Great Outdoors initiative, it exemplifies a 21st Century vision of landscape scale conservation for the country built on science and strong partnerships with communities.”
The Fish and Wildlife Service will manage the new conservation area as part of the National Wildlife Refuge System, Ashe said.
