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.
Dr. Marcia McNutt to Provide Status Update on Flow Rate Technical Group's Scientific Efforts to Measure the Flow from BP Oil Spill

TODAY, Thursday, June 10, 2010, at 4:45 pm EDT, Dr. Marcia McNutt, the Director of the U.S. Geological Survey and Chair of the National Incident Command's Flow Rate Technical Group, will discuss the status of the work of several scientific teams that are using various methodologies to estimate the amount of oil that is leaking from BP's well into the Gulf of Mexico. Working together with Energy Secretary Steven Chu and scientists from the Department of Energy, Dr. McNutt expects that the Flow Rate Technical Group will have an updated flow rate estimate in the coming days that brings together new data from the well and analysis from several scientific methodologies. News media may participate in the teleconference by dialing 1-877-601-3555 and providing the access code FLOW RATE.
