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.

Mine tailings, washed from an impoundment at the Waco Subsite, shown here in January 2004, are a source of hazardous substances releases at the Waco Subsite of the Cherokee County NPL site in southeastern Kansas. Photo credit: John Miesner, FWS.
On June 6, 2012, the U.S., on behalf of the Department of the Interior, and the State of Kansas settled natural resource claims against E.I. du Pont de Nemours and Company for injuries to natural resource and natural resource services caused by hazardous substances releases into navigable waters at the Waco Subsite of the Cherokee County NPL site in southeastern Kansas. This settlement was embodied in a Consent Decree entered by the U.S. District Court for the District of Kansas.
The natural resource trustees in this case include the U.S. Department of the Interior, represented by U.S. Fish and Wildlife Service, and the State of Kansas, represented by Department of Health and Environment and the Secretary of the Department of Health and Environment, and.
U.S. Environmental Protection Agency placed the Cherokee County Superfund Site on the National Priorities List in 1983. The Site, comprising 115 square miles in southeastern Kansas near the borders with Oklahoma and Missouri, has been divided into 7 subsites: Badger, Baxter Springs, Crestline, Galena, Lawton, Treece and Waco. The Waco Subsite, located about 6 miles north of Riverton, Kansas, covers about 560 acres. Cow Creek and an unnamed tributary to Cow Creek run through the Waco Subsite.
Mines and other properties owned by E.I. du Pont de Nemours and Company and its predecessors-in-interest have released and continue to release hazardous substances -- including lead, cadmium and zinc -- into the environment at the Waco Subsite and into Cow Creek. These hazardous substances releases have injured natural resources including: groundwater, surface water, sediments, terrestrial resources, resident and migratory birds, fish, macroinvertebrates and other biota.
Under the final settlement in the Consent Decree, E.I. du Pont de Nemours and Company will:
Pay $181,852.00 to be used by the natural resource trustees for the assessment, planning, restoration, rehabilitation and/or acquisition of the equivalent of injured natural resources at the Waco Subsite and area surface waters and for the long term management of these restored natural resource in accordance with the Cherokee County Restoration Plan;
Pay $12,505.00 plus interest to reimburse DOI for associated damage assessment costs; and,
Pay $58,382.00 to reimburse the State for associated damage assessment costs.
The total monetary value of the settlement is $252,739.00.
