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.

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.

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.
Statement of Assistant Secretary Strickland Regarding Court Ruling on the Northern Rocky Mountain Gray Wolf

WASHINGTON – Assistant Secretary of the Interior for Fish and Wildlife and Parks Tom Strickland today issued the following statement regarding a decision in U.S. District Court on the Northern Rocky Mountain gray wolf population:
“For more than 15 years, the U.S. Fish and Wildlife Service, state wildlife agencies, tribes, conservation organizations, ranchers and other landowners have worked hard to recover gray wolves in the Northern Rocky Mountains. Our collective efforts have brought this population to the point where it no longer requires Endangered Species Act protection.
“Despite this extraordinary success, today's ruling means that until Wyoming brings its wolf management program into alignment with those of Idaho and Montana, the wolf will remain under the protection of the Endangered Species Act throughout the northern Rocky Mountains. Since wolves in the Northern Rocky Mountains are now again subject to ESA protection, in the days ahead we will work closely with Idaho and Montana to explore all appropriate options for managing wolves in those states.
“Reintroduced from Canada, in the mid-1990s, to remote areas of central Idaho and Yellowstone National Park, the wolf population flourished and reached sustainable recovery levels as early as 2002. It has continued to grow and has now far surpassed these recovery plan targets.
“The Service's decision to delist the wolf in Idaho and Montana reflected the strong commitments from the states of Idaho and Montana to manage gray wolves in a sustainable manner. Today's ruling makes it clear this wolf population cannot be delisted until the State of Wyoming has instituted an adequate management program, similar to those of Idaho and Montana.
“In the meantime, we will continue to work closely with the states, tribes, conservation organizations, and ranchers and other landowners to manage wolves and ensure the species continues to thrive and coexist with livestock, other wildlife populations, and people.”
