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.

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.

ST. LOUIS, MO – On Friday, August 2, Secretary of the Interior Sally Jewell, Transportation Secretary Anthony Foxx, U.S. Senator Claire McCaskill, and state and city officials and local partners will meet in St. Louis to break ground on the ‘Park over the Highway' project, the first component in the CityArchRiver 2015 plan to revitalize and improve access to the Jefferson National Expansion Memorial, home of the Gateway Arch.
The ‘Park Over the Highway' will feature a landscaped structure over Interstate 70 that will improve pedestrian accessibility and create a model urban national park, providing increased opportunities for outdoor recreation and inviting more people to fully enjoy the natural beauty, culture, and history of the area.
The project component is being funded through a $20 million federal grant matched by $25 million from the state and $10 million from the CityArchRiver 2015 Foundation. Overall, the CityArchRiver 2015 initiative is expected to boost visitation to the memorial. CityArchRiver also expects the initiative to support an estimated 4,400 new permanent jobs in the region.
