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.
Department of the Interior and Department of Commerce Submit Draft Legislation to Conserve Oceanic Birds
Last edited 4/25/2016
WASHINGTON, D.C.--The Department of the Interior and the Department of Commerce today forwarded to Congress for consideration draft legislation titled the “Albatross and Petrel Conservation Act of 2009” to protect certain oceanic birds.
“The albatross and the petrel soar and glide, sometimes tens of thousands of miles each year. Though remarkably resilient, these majestic, well-traveled ocean wanderers face increasing threats to their survival,” said Deputy Secretary of the Interior Lynn Scarlett. “Today, we transmit to the Congress draft legislation to implement the ‘Agreement for the Conservation of Albatrosses and Petrels' that, if passed by the Congress, will help to secure their future.”
This important international agreement entered into force on Feb. 1, 2004. On Sept. 26, 2008, President Bush transmitted the agreement to the U.S. Senate, recommending that it give its advice and consent to United States accession.
The draft legislation provides the United States, primarily through the Departments of the Interior and Commerce, with authority to adopt and implement conservation and management measures to address the most pressing threats to albatrosses and petrels in the wild, including habitat disturbance, nesting habitat degradation and loss, changes in food supply, pollution and marine debris, impacts from non-native species, and the incidental bycatch of birds in fisheries.
