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: Secretary Salazar, Governor Hickenlooper Outline Conservation Vision for Colorado
Office of the Secretary
Announce Three America's Great Outdoors Projects at Ribbon-Cutting for Rocky Mountain Arsenal National Wildlife Refuge Visitor Center
COMMERCE CITY, CO — Secretary of the Interior Ken Salazar today joined Colorado Governor John Hickenlooper at the ribbon-cutting for the Rocky Mountain Arsenal National Wildlife Refuge Visitor Center to announce that they will partner together to advance three conservation initiatives in Colorado as part of President Obama's America's Great Outdoors Initiative. Identified by the State of Colorado, each project exemplifies the heart of America's Great Outdoors by reconnecting Americans – especially young people – to their natural heritage.
“Colorado is setting an example for the rest of the nation as to the value of recreation and conservation to our economy and quality of life,” said Secretary Salazar. “Today begins a new chapter in the strong partnership between the State of Colorado and the Department of the Interior, and I look forward to working with the Governor to help turn these projects into reality.”
“The new Rocky Mountain Arsenal visitor center and three conservation initiatives will further showcase the natural beauty we are fortunate to live in and share with visitors from around the word,” said Governor Hickenlooper. “Under Secretary Salazar's leadership, from Great Outdoors Colorado to America's Great Outdoors, we are creating partnerships and leveraging the state and nation's intellect and creativity to build and protect our natural heritage.”
President Obama's America's Great Outdoors initiative seeks to work with local communities to create a new conservation and recreation ethic for the 21st Century. As part of the initiative, the Administration held 51 listening sessions across the country that generated valuable input and ideas on how best to protect and enhance the places most important to local communities.
Secretary Salazar has continued this national dialogue with Governors across the nation about how the federal family can support important, local conservation and recreation priorities.
Colorado's three priority projects align with the goals of the America's Great Outdoors initiative to establish or enhance great urban parks; restore important river corridors; and conserve rural, working landscapes. Additional information on each project can be found below.
Yampa River Basin Project: Interior and other federal agencies will work with the State, local stakeholders, private landowners and other partners to help conserve healthy lands and waters in the Yampa River Basin. Through conservation easements, stewardship projects and other tools, the Yampa River Basin project will build on initiatives to work with local ranchers and farmers to preserve working ranches and farms and wildlife habitat, and promote outdoor recreation and tourism. A full description of the Yampa River Basin is here.
San Luis Valley Project: Interior and other federal agencies will work with the State, local stakeholders, private landowners and other partners to help conserve healthy lands and waters and promote tourism in the San Luis Valley and the Rio Grande River Corridor. The AGO project will build upon local and federal efforts to conserve the Valley's vibrant ranching community and protect important wildlife resources and wetland habitat in southern Colorado on a landscape scale. A full description of the San Luis Valley Project is here.
Denver Metro Greenway Project: Interior and other federal agencies will work with the State, stakeholders and other partners to enhance the Denver metropolitan area parks, open spaces and trails, and to create linkages to creeks, river corridors and state and federal parks. Secretary Salazar outlined a vision to potentially create a "Rocky Mountain Greenway" – an uninterrupted trails/transportation link between the three National Wildlife Refuges in the metro region (the Rocky Mountain Arsenal NWR, the Two Ponds NWR, and the Rocky Flats NWR), the Rocky Mountain National Park and community trails systems in between, and connecting with the Denver metro area's other trail systems. A full description of the Denver Metro Greenway Project is here.
Today's announcement occurred at the Rocky Mountain Arsenal National Wildlife Refuge Visitor Center dedication ceremony. The ribbon-cutting for the new, eco-friendly building was a culminating event in the transformation of the Arsenal from a Superfund site to one of the nation's premier urban national wildlife refuges. The visitor center, expected to receive more than 200,000 visitors each year, was completed with American Recovery and Reinvestment Act funds. The facility is situated at the southwestern boundary of the refuge, adjacent to Dick's Sporting Goods Park, home of the Colorado Rapids.
