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.

Federal Subsistence Board Closes Stikine River Subsistence Chinook Salmon Fishery
The Federal Subsistence Board has closed the May 15-June 20, 2014 subsistence Chinook salmon fishery on the Stikine River and delegated authority to the Wrangell District Ranger to reopen the fishery if the in-season Chinook salmon terminal area abundance estimate allows a directed fishery.
The 2014 pre-season return estimate for the Stikine River is 26,000 Chinook salmon. The U.S./Canada Pacific Salmon Treaty stipulates that a directed Chinook salmon subsistence fishery is not authorized if the pre-season run estimate is less than 28,100 Chinook salmon. As a result, the Board has closed the 2014 subsistence Chinook salmon fishery. The Board also authorized the Wrangell District Ranger to reopen the season if the weekly in-season abundance estimate exceeds 24,500 Chinook salmon, as allowed for in the Treaty. The closure of the Chinook salmon fishery does not affect other Stikine River Federal subsistence fisheries beginning June 21, 2014.
