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 Phase II Draft Restoration Plan for Injured Natural Resources at Cyprus Tohono Mine, Tohono O’odham Nation

Hazardous substances releases at evaporation ponds and tailings impoundments at the Cyprus Tohono Mine site, shown here, on the Tohono O’odham Nation in southern Arizona, have injured natural resources including groundwater and migratory birds. Photo credit: Freeport-McMoRan.
On October 11, 2012, the federal and Tribal natural resource trustees opened a 45-day public comment period on “Phase II: Draft Restoration Plan and Environmental Assessment for the Cyprus Tohono Mine Natural Resource Damage Assessment, Sif Oidak District, Tohono O’odham Nation.” This Phase II Draft Restoration Plan presents alternatives and selects a preferred alternative to restore natural resources injured by hazardous substances releases from the Cyprus Tohono Mine site on the Tohono O’odham Nation.
The natural resource trustees in this case include:
Tohono O’odham Nation, represented by Tohono O’odham Department of Natural Resources, Tohono O’odham Attorney General, North Komelik Community and Sif Oidak District; and,
U.S. Department of the Interior, represented by Bureau of Indian Affairs and U.S. Fish and Wildlife Service.
Cyprus Tohono Mine is an open pit, copper mining operation on 4,180 acres of leased land near the community of North Komelik in the Sif Oidak District on the Tohono O’odham Nation, southwest of Casa Grande in southern Arizona. The mining site lies in arid Sonoran Desert in the Santa Rosa Basin southwest of the Slate Mountain Range. Hazardous substances -- including various metals, sulfate, sulfuric acid and radionuclides -- released into on-site evaporation ponds, leach residue ponds and a pit lake injured natural resources and natural resource services.
In July 2009, the trustees partially settled natural resource damage claims in a Consent Decree with Cyprus Tohono Corporation. The monetary portion of settlement had two phases. Phase I provided $78,710 compensation for past lost use of groundwater. Phase II provided $746,290 compensation for past, non-groundwater, natural resource damages. This Phase II Draft Restoration Plan, after examining various alternatives, proposes to apply this Phase II funding to create new wetlands and/or enhance existing wetlands to create habitat for migratory birds.
Written comments on the Phase II Draft Restoration Plan must be received by the U.S. Fish and Wildlife Service in Phoenix, Arizona, by Monday, November 26, 2012.
