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.
Every day someone like you becomes a wildland wildfire fighter, a teacher, a trail-builder, a museum curator, or a park ranger. Discover your opportunities in national parks. Come to play. 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.

WASHINGTON, DC -- Secretary of the Interior Ken Salazar today announced that the Department will commit more than $89.8 million for a variety of restoration and improvement projects throughout Nevada and Lake Tahoe. The funding is a result of the Southern Nevada Public Land Management Act (SNPLMA) which uses proceeds from sales of federal land in Clark County, Nevada, to fund environmental restoration, conservation and public recreational projects throughout the state. The Department of the Interior has contributed more than $3 billion to key restoration projects throughout Nevada, including more than $350 million for Lake Tahoe Basin restoration in Nevada, since the Act's passage in 1998.
“Nevada's natural beauty and unique landscapes should be protected for future generations and I am pleased to commit nearly $90 million for important projects throughout the state,” Salazar said. “The Department of the Interior remains committed to working closely with our local, state and Federal partners to restore and enhance these specials areas for the benefit of all who live in and visit the state.”
“The BLM is committed to ensuring that the American people benefit from their public lands,” said Bureau of Land Management Director Bob Abbey, who oversees the public land sales. “Through SNPLMA, the BLM contributes to the efforts to improve landscapes, restore wildlife habitat, protect vital water resources and other sensitive areas, and develop new recreational facilities in the magnificent State of Nevada.”
The funding is contained in Round 11 expenditures under the Act and includes more than $76.7 million for projects throughout Nevada in the following categories:
Parks, Trails & Natural Areas - $14,722,396
Capital Improvements - $9,647,508
Conservation Initiatives - $1,184,836
Environmentally Sensitive Land Acquisitions - $11,267,250
Hazardous Fuels Reduction and Wildfire Prevention - $3,949,800
