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.
Salazar Announces Nearly $650 Thousand in Grants to Conserve Critically Endangered Wildlife Around the Globe

WASHINGTON, D.C. -- Secretary of the Interior Ken Salazar today announced nearly $650,000 in grants to conserve and protect 30 critically endangered species in 15 countries around the world ranging from the Siamese crocodile in Asia to the Siberian crane in Russia to the Ethiopian wolf in Africa.
The 24 grants, administered by the U.S. Fish and Wildlife Service, will leverage more than $1.2 million in matching funds from partner organizations.
“The United States is committed to ensuring that birds, mammals, amphibians, and reptiles not only survive the threat of extinction but also recover to the point where we have healthy populations,” Salazar said. “Working with many partners, we are investing in recovery and conservation efforts that will help endangered animals and their habitat around the world. We have a shared responsibility to help safeguard our planet's remarkable biodiversity."
The grants are being awarded through the Service's new Critically Endangered Animals Conservation Fund. They are a one-time global funding opportunity developed by the International Affairs program to augment the Wildlife Without Borders Species and Regional conservation programs.
“These grants are aimed at providing vital support for highly imperiled species and habitats around the world,”According to Service Director, Sam Hamilton. “They focus on collaborating with local communities, partner organizations, universities, and government agencies world-wide.”
Three of the funded projects are aimed at combating the spread of a deadly fungus, Batrachochytrium dendrobatidis (Bd), which is wiping out entire populations of amphibians, primarily frogs, in the Americas. These research projects could lead to a cure for the disease that has caused the extinction of nearly one-third of the frogs and salamanders in the areas where it has spread.
Perhaps the most promising project is the attempt to confer resistance to the fungus on affected species through the use of fungal-resistant bacteria. Another will establish a captive population of 40-60 poison-dart frogs to provide safety to the species while the deadly fungal scourge plays itself out in the wild.
On the African continent, steps will be taken to conserve the last remaining population of Ethiopian wolves, which number approximately 450 individuals. The hope is to inoculate free-ranging Ethiopian wolves with an oral rabies vaccine that reduces the devastating impact of the disease conferred upon them at an increasing rate, by domestic and feral dogs.
Of the 24 projects selected for funding, 11 focus on species in Asia, including Oceania; seven on Africa, including Madagascar; and six on Latin America and the Caribbean.
Nine of the critically endangered species targeted by the grants are reptiles, including the Siamese crocodile, Antiguan racer, and river terrapin; seven are birds, including the Siberian crane, Polynesian ground-dove, and Madagascar pochard; and five are mammals, including the giant sable and the duiker, in addition to the Ethiopian wolf. More than 10 species of amphibians are targeted by the three amphibian projects, including the Panamanian golden frog and other critically endangered poison-dart species.
