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.

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 Highlights 10 Projects in Pacific Northwest and Western States as America's Great Outdoors Rivers
Interior will leverage resources to support river initiatives in every state and District of Columbia
WASHINGTON – Secretary of the Interior Ken Salazar today identified river projects in 10 western and Pacific Northwest states to serve as models of the America's Great Outdoors River Initiative to conserve and restore key rivers across the nation, expand outdoor recreational opportunities and support jobs in local communities.
The 10 river projects are part of a list of 51 ongoing projects that the Secretary is highlighting nationwide, one in each state and the District of Columbia. Ranging from the Elwha River Fish Passage Project in Washington to the Colorado River Heritage Greenway Park in Nevada, today's projects were selected to provide examples for how communities across America can restore and reconnect with the rivers in their backyards.
“Across the country, we are working hand in hand with states, tribes, local communities and other partners to revitalize our nation's rivers and expand the opportunities for people to fish, swim, boat, and otherwise connect with the great outdoors,” Salazar said. “These on-going projects demonstrate how the federal family can be an effective conservation partner for community-led efforts to improve our rivers, which are the lifeblood of our communities and our economies.”
A map and more detailed descriptions of the river initiatives highlighted by Salazar can be accessed here. Additional river projects across the nation will be announced in the coming days.
The U.S. Fish and Wildlife Service is working with many federal, tribal, state and local agencies, nongovernmental organizations, and private landowners to restore fish passage, improve riparian habitat, and support the community Stream Watch program on the Kenai River, which is one of Alaska's premier recreation destinations for tourists and residents.
The Red Bluff Fish Passage Improvement Project is a partnership between Bureau of Reclamation and the Tehama-Colusa Canal Authority. It is the culmination of over 40 years of efforts by various stakeholders to find a balanced solution that improves fish passage and continues to deliver irrigation water to high-value cropland that produces over $250 million in crops per year and contributes $1 billion annually to the regional economy.
The Bureau of Land Management is working with the Dolores River Partnership - a two-state, citizen driven partnership – to improve fish habitat, restore riparian habitat, increase stream flows, reduce wildfire risks, develop education and stewardship opportunities, and expand opportunities for youth employment.
The U.S. Fish and Wildlife Service and other Federal agencies are working with many state and local agencies, and non-governmental organizations to restore the biological, socioeconomic, and cultural productivity of the lower He‘eia watershed, which contains the highest numbers and greatest diversity of fish, marine invertebrates, and native marine algae on the island.
The Bureau of Reclamation along with other federal, tribal, state and local agencies, non-governmental organizations, and private corporations are creating spawning habitat for Chinook salmon, as well as steelhead and other native fish, along a section of Yankee Fork that was drastically altered by mining and dredging activities.
The Bureau of Reclamation and other federal, state, and local agencies, and non-governmental organizations are collaborating on river restoration, trails and access, picnic sites, shade shelters, fishing piers, equestrian facilities and other projects on a 1,191 acre public park serving the states of Nevada, Arizona and California.
The watershed-scale partnership of federal, state and local agencies and non-governmental organizations, including the Bureau of Land Management, are working to expand environmental and recreational opportunities, and protect critical habitat on the Sandy River, which will benefit the one-third of Oregon's population that lives within 30 minutes of the project, and the federally-listed spring Chinook, winter Steelhead, and winter Coho.
The Bureau of Land Management, other Federal agencies, and non-governmental organizations are cooperating on recreation, riparian restoration, and species recovery projects that utilize Youth Corps and other volunteers, and will benefit 200 species of migratory birds and several rare fish along the Escalante River.
The National Park Service and other federal, tribal, state and local agencies are working to reopen more than 70 miles of pristine spawning and rearing habitat for five species of Pacific salmon on the Elwha River, with salmon populations predicted to swell from 3,000 to 400,000 – returning the Elwha River to the Pacific Northwest's most productive salmon streams.
The Bureau of Land Management is working with state and local agencies to enhance wildlife habitat through invasive species control and reforestation, and to improve public access along the North Platte River, which offers spectacular fishing, paddling, waterfowl hunting and wildlife observation opportunities.
As part of America's Great Outdoors Rivers, Interior Department agencies – including the National Park Service, the Bureau of Land Management, the Bureau of Reclamation, and the U.S. Fish and Wildlife Service – will work with states and communities to advance river restoration and recreation by providing technical and other assistance through existing programs and staff, and by leveraging non-federal investments.
“America has more than 3.6 million miles of rivers and streams, and nearly every American lives within a mile of a river or stream, making them some of the nation's most important recreational and ecological assets,” Salazar added. “America's Great Outdoors Rivers will help fulfill President Obama's vision for healthy and accessible rivers as we work to restore and conserve our nation's treasured waterways.”
Rivers are economic engines for many local communities, supporting recreation and tourism industries by providing opportunities for boating, fishing and hunting, hiking, camping, swimming, and numerous other outdoor activities. Salazar noted that the outdoor industry creates an estimated 6.5 million jobs in the United States and pumps an estimated $730 billion a year into our nation's economy.
Salazar unveiled America's Great Outdoors Rivers in January as part of President Obama's overall America's Great Outdoors Initiative to work with communities across the country to establish a conservation and recreation agenda for 21st century and to reconnect people, especially young people, to the great outdoors.
The goals of America's Great Outdoors Rivers include protecting and restoring America's rivers for people and wildlife and enhancing river recreation that supports jobs in tourism and outdoor recreation.
Under the initiative, Salazar issued a Secretarial Order in February establishing a National Water Trails System, creating a network of designated water trails on rivers across the country that will help facilitate outdoor recreation, especially around urban areas, and provide national recognition to existing, local water trails. He designated the Chattahoochee River Water Trail, which encompasses 48 miles of river within the Chattahoochee River National Recreation Area in Georgia, as the first National Water Trail.
In March, Salazar, Secretary of Agriculture Tom Vilsack, and Secretary of Commerce John Bryson signed a memorandum of understanding implementing the National Fish Habitat Action Plan to assist state and local governments, landowners, and community groups in protecting and restoring waterways and fisheries.
