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.

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.

SANDY SPRINGS, GA—On Wednesday, August 29, 2012, Acting Assistant Secretary for Fish and Wildlife and Parks Rachel Jacobson will visit the Chattahoochee River National Recreation Area to meet with park managers and local officials from the Atlanta Metropolitan Area to discuss how the park's recent designation as a National Water Trail will boost tourism and fuel the local economy.
Following the morning meeting, Jacobson and park managers will paddle down the most popular section of the 48-mile National Recreation Area, from Powers Island to Paces Mill.
Members of the media are invited to join Jacobson and park managers for the float, which will be followed by a brief media availability. The float will offer a unique, first-person perspective to develop an in-depth story on the new National Water Trail System and its potential impact on recreation and tourism.
Rafts and equipment for the media will be provided.
