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.

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.
Settlements at two different Superfund sites in Connecticut allowed the Department to initiate multiple restoration projects that have led to improvements in fish habitats, streamside habitats, and greater public access. In one case, contaminants from the Yaworski Lagoon Superfund Site near Plainfield, CT, had adversely affected riverine habitat downstream from the Moosup River. At this site, the U.S. Fish and Wildlife Service, working with local partners, utilized a $40,000 settlement to remove an antiquated cast iron pipe that crossed the stream, forming a small dam that blocked upstream and downstream fish passage. The removal of the pipe reconnects more than 5 miles of riverine habitat, benefiting resident fish and other aquatic organisms.
Trustees from the Fish and Wildlife Service also worked with State and local governments and organizations in Connecticut to utilize funds from a settlement with the General Electric Company. The settlement compensates the public for injuries stemming from PCB contamination generated upstream in the Housatonic River watershed near Pittsfield, Massachusetts. The first acquisition, in New Milford, CT, is a 25-acre parcel with over a quarter mile of river frontage. The property will be cleared of invasive plants and become a town park, managed primarily for wildlife habitat and wildlife viewing, as well as flood control. The property contains a floodplain forest and intermittently flooded grasslands, which will also serve as an outdoor classroom for schools and Scout groups. The second acquisition area encompasses 3.5 acres along the banks of the Naugatuck River, a tributary to the Housatonic. Residents of the town of Harwinton overwhelmingly supported the purchase of this riverfront property that was the historic site of early water-powered business development in the region. The property will be managed locally for public fishing access.
