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 and Partners Purchase Conservation Easement on Housatonic Riverfront Property in Litchfield County, Connecticut

This riverfront property in Litchfield County, Connecticut, along the Housatonic River, is now protected by a conservation easement purchased on February 7 by the natural resource trustees and cooperating partners.

On February 7, 2012, the Sharon Land Trust and the Housatonic Valley Association, using funds from the State and federal natural resource trustees for the Housatonic River Basin Restoration Trustee Council, together with other partner organizations, completed the purchase of a conservation easement to permanently protect 20 acres of farmland along the Housatonic River, near Sharon in Litchfield County, Connecticut.
This restoration project implements part of the publicly-reviewed “Housatonic River Basin Final Natural Resources Restoration Plan.” The Restoration Plan seeks to restore natural resources and natural resource services injured by the release of hazardous substances – in this case, chemical wastes and PCBs – into the Housatonic River system by General Electric Company from its facility in Pittsfield, Massachusetts.
The natural resource trustees include Connecticut Department of Energy and Environmental Protection, Massachusetts Executive Office of Energy and Environmental Affairs, National Oceanic and Atmospheric Administration and Department of the Interior, represented by the U.S. Fish and Wildlife Service. Partners in this restoration project include the property owner, Mr. Denny Frost, The Sharon Land Trust, Housatonic Valley Association, Newman’s Own Foundation, Cornwall Conservation Trust and individual donors.
The property has 1,480 feet of riverfront and a unique, ecologically important kettle pond. A kettle pond is formed by a retreating glacier leaving an exposed water table in a geologic depression. The resulting kettle-shaped pond has no surface water inlet or outlet and, consequently, no fish. This absence of fish allows amphibians, like woodland frogs, newts and salamanders, to thrive. The open fields and riparian borders of the property provide habitat for migratory birds.
The Housatonic River Basin Restoration Trustee Council will also fund the construction of a low-impact trail along the riverfront on the property linking other nearby protected riverfront lands. This stretch of the Housatonic River annually attracts thousands of recreational boaters, hikers, fishermen, nature photographers, bird watchers and other visitors.
