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.
Historically, the U.S. Fish and Wildlife Service and its co-trustee partners (the Wisconsin Department of Natural Resources, the Oneida Tribe of Indians of Wisconsin, and the Menominee Indian Tribe of Wisconsin) on the Fox River/Green Bay Natural Resource Trustee Council have been very active in developing and implementing restoration projects to compensate the public for injuries to multiple natural resources and diminished recreational fishing activities stemming from PCBs released into the Lower Fox River. To date, the Trustee Council has implemented over 100 restoration projects utilizing $36 million in settlement funds matched by an additional $22 million from conservation partners.
In 2010, Trustee Council conservation partners received $2.4 million in grant funding from EPA, through the Great Lakes Restoration Initiative (GLRI). The GLRI is a major federal initiative, the largest investment in the Great Lakes in two decades, addressing contaminated sediments and other major threats to the Great Lakes. The Trustees are matching the EPA grant with $1.7 million of NRDA settlement funding to implement two major restoration projects. In the first project, the Trustees and EPA provided $2.6 million to Brown County, Wisconsin, to restore the Cat Island Chain, a 272-acre chain of islands along the western shore of Green Bay. The reestablishment of the island chain will create a wave shadow restoring more than 620 acres of high quality shallow water habitat for diverse populations of native fishes, waterbirds, and mammals, and it will create a major stopover for migrating waterfowl. In the second project, the Trustees and EPA awarded $1.5 million to Brown County and Oconto County to restore wetland and floodplain habitat important for northern pike spawning on the west shore of Green Bay. The restoration of the riparian buffers along with permanent conservation easements will improve adult pike access to upstream, inland wetland areas used for spawning and rearing sites. The restored buffers will also limit sediments, nutrients, and pesticides entering into streams from cropland thereby protecting habitat and quality plankton production areas needed for feeding young pike.
EPA awarded an additional $2.5 million for three other projects within the Fox River/Green Bay watershed that will complement the Trustee Council’s restoration goals and activities. These projects will create buffer strips to reduce sedimentation in one drainage basin, restore stream habitat in a second drainage basin, and control invasive plants along the coast of Lake Michigan to improve fish and wildlife habitat.
