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 60-Day Public Comment Period on Draft Restoration Plan for Portage Creek and Operable Unit 1, Kalamazoo River NPL Site, Michigan

On April 4, 2012 the federal and State natural resource trustees opened a 60-day public comment period on the “Draft Restoration Plan and Environmental Assessment, Portage Creek and Operable Unit 1 – Allied Paper Property, Allied Paper, Inc./Portage Creek/Kalamazoo River Superfund Site.” The natural resource trustees in this case include:
State of Michigan, represented by Department of the Attorney General, Department of Environmental Quality and Department of Natural Resources;
U.S. Department of Commerce, represented by National Oceanic and Atmospheric Administration; and,
U.S. Department of the Interior, represented by U.S. Fish and Wildlife Service.
In 1990, the U.S. Environmental Protection Agency placed the Kalamazoo River in Kalamazoo and Allegan Counties, Michigan, on the National Priorities List because of PCBs contamination in the sediment and floodplain soils. The NPL site encompasses a 3-mile stretch of Portage Creek and the lower 80-mile stretch of the Kalamazoo River to the mouth of the River at Lake Michigan.
EPA has divided the Kalamazoo River NPL site into five Operable Units plus two paper mill properties. Operable Unit 1, including the Allied Paper property and the former Bryant Mill Pond area, is located within the City of Kalamazoo, next to Portage Creek. The natural resource trustees have concluded that natural resources -- including surface water, sediment, soils, fish, benthic invertebrates, birds and mammals -- have been injured by hazardous substances releases at Operable Unit 1 into Kalamazoo River and Portage Creek and their floodplains.
The purpose of the proposed restoration actions in this Draft Restoration Plan and Environmental Assessment is to compensate the public for injuries to natural resources and natural resource services. The natural resource trustees do not necessarily expect to be able to implement all of the proposed restoration projects described in the Draft Restoration Plan. Ultimately, the restoration projects implemented will depend on available funding from the settlement of natural resource damage claims with responsible parties. Public input regarding favored potential restoration projects is encouraged.
The deadline for submitting written comments to the Michigan Department of Environmental Quality on the Draft Restoration Plan and Environmental Assessment is Friday, June 1, 2012.
