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.
Assistant Secretary Strickland Lauds House Passage of the Asian Carp Prevention and Control Act

WASHINGTON -- Assistant Secretary of the Interior for Fish and Wildlife and Parks Tom Strickland today issued a statement lauding House passage of S. 1421, the Asian Carp Prevention and Control Act, which lists bighead carp as an injurious species under the Lacey Act. S. 1421 passed the Senate by unanimous consent on November 17, 2010 and passed the House by a voice vote.
“Along with other invasive Asian carp species, the bighead carp poses an immediate and significant threat to the nation's freshwater fisheries, especially the Great Lakes,” Strickland said. “While normally we would list an injurious species under administrative rulemaking, the urgency of the situation called for swift action by Congress so that we can prevent this voracious fish from spreading to new areas and overwhelming recreational and commercial fisheries by effectively starving native fish.”
Under the Lacey Act, the Secretary of the Interior is authorized to regulate the importation and interstate transport of species determined to be injurious to humans, the interests of agriculture, horticulture or forestry, and the welfare and survival of wildlife resources of the United States. Species listed as injurious may not be imported or transported across state lines by any means without a permit issued by the U.S. Fish and Wildlife Service. The penalty for an injurious wildlife Lacey Act violation is up to six months in prison and a $5,000 fine for an individual or a $10,000 fine for an organization.
The Fish and Wildlife Service administratively listed three other Asian carp -- the silver, black and large-scale silver carp -- as injurious species under the Lacey Act in 2007.
Listing bighead carp as an injurious species was called for in the Asian Carp Control Strategy Framework released by the Obama Administration in February of this year. This framework of coordinated short- and long-term actions unifies Federal, state and local agencies, known as the Asian Carp Regional Coordinating Committee (ACRCC), in an unparalleled effort to prevent Asian carp from establishing populations in the Great Lakes. USFWS is a member of the ACRCC. More information on the framework and the ACRCC can be found on the website at www.asiancarp.org.
