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.
Permits will not be issued to take Chinook salmon in the Situk River until further notice

YAKUTAT, Alaska–Yakutat District Ranger Lee Benson has announced that he is acting immediately to protect Chinook salmon in the Situk River near Yakutat. The district ranger, as in-season manager, will not issue Federal Subsistence Fishing permits for the taking of Chinook salmon in the Situk River unless the Alaska Department of Fish and Game (ADF&G) estimates that the weir count of large, three ocean-age and older, Chinook salmon will be within their biological escapement goal range and they reopen the State's subsistence fishery for Chinook salmon in the Situk-Ahrnklin Inlet. The Alaska Board of Fish has set the biological escapement goal range between 450 and 1,050 large Chinook salmon in the Situk River and State biologists have forecasted a return of 826 large Chinook salmon to the river in 2014. Subsistence fishing for species other than Chinook salmon in the Situk River continues to be permitted but the use of gillnets or bait when fishing with rod and reel will not be permitted at this time. All Chinook salmon incidentally caught must be immediately released back into the water with as little handling as possible.
