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.
Trustees Open 45-Day Public Comment Period on Draft Injury Assessment Plan for Natural Resources at Hanford NPL Sites, near Richland, Washington

Columbia River, shown here, borders the 586-square-mile Hanford Site in south-central Washington, on the east and north. Potential injuries caused by hazardous substances releases from the Hanford NPL sites to economically and culturally important fish species in the River will be studied in the Injury Assessment Plan.

On November 15, 2012, the federal, state and tribal natural resource trustees opened a 45-day public comment period on the draft “Hanford Natural Resource Damage Assessment Injury Assessment Plan” for the Hanford Nuclear Reservation NPL sites, northwest of Richland, Washington.
The natural resource trustees in this case include:
Confederated Tribes and Bands of the Yakama Nation;
Confederated Tribes of the Umatilla Indian Reservation;
Nez Perce Tribe;
State of Oregon, represented by Oregon Department of Energy;
State of Washington, represented by Washington Department of Ecology in consultation with Washington Department of Fish and Wildlife;
U.S. Department of Commerce, represented by National Oceanic and Atmospheric Administration;
U.S. Department of Energy; and,
U.S. Department of the Interior, represented by Bureau of Indian Affairs, Bureau of Reclamation and U.S. Fish and Wildlife Service.
The Hanford Nuclear Reservation was established by the United States in 1943 as part of the Manhattan Project on 586 square miles of land in south-central Washington. Columbia River borders the Site on the east and north. During the production of materials for nuclear weapons, the Site produced large quantities of wastes containing hazardous substances and radioactive materials. These wastes were managed by storing them on land and releasing them to ponds and ditches.
Over time, these wastes containing hazardous substances leaked and were released to the land, air, groundwater and surface water, including Columbia River. A preliminary accounting of these hazardous substances include: a variety of metals and radioisotopes and organic compounds including solvents, pesticides and PCBs. In 1988, U.S. Environmental Protection Agency placed Hanford on the National Priorities List and created four separate NPL sites: the 100 Area, 200 Area, 300 Area and 1100 Area. Production activities at the Site stopped in 1989 and work shifted to cleanup of the contamination which will continue for decades.
The Hanford Site has unique terrestrial and aquatic ecosystems that support at least 725 plant species, 40 mammal species, over 200 bird species and a variety of amphibians, reptiles and invertebrates. Columbia River, which borders the Site, supports economically and culturally important fish species such as Chinook salmon, coho salmon, steelhead, white sturgeon and Pacific lamprey.
Potential injuries to these natural resources and associated natural resource services caused by hazardous substances releases are the focus of Injury Assessment Plan. This Draft Injury Assessment Plan represents the trustees’ current understanding of the studies necessary to determine and quantify the injuries.
Written comments on the Draft Injury Assessment Plan must be received by Washington Department of Ecology by Monday, December 31, 2012.
