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.

Remarks of Secretary of the Interior Ken Salazar
Eighth Annual Commemoration in Honor of the Heroic Passengers of Flight 93
September 11, 2009
On behalf of President Barack Obama and a grateful nation, today we say to the families of our Flight 93 heroes, “We will never forget.”
The heroes of Fight 93, who here gave their lives, will forever inspire us by their example of their triumph of good over evil.
These fields, where the heroes of Flight 93 perished, are hallowed ground for a grateful nation. We honor the courage and sacrifice of the passengers and crew who gave their lives that day.
The events of September 11, 2001, revealed the extraordinary bravery of ordinary men and women. Their acts of courage, sacrifice, and heroism will never be forgotten.
We also honor and thank the community of Shanksville who were also victims on September 11, 2001 and who have sacrificed so much since then. Three hundred sixty-five days a year, volunteers from the community stand guard at this temporary memorial. The Families of Flight 93 and the people of Shanksville are now family.
This temporary memorial, these ceremonies on this makeshift pad, will be forever etched in our hearts, minds and memories.
The Flight 93 Memorial will soon stand in eternal tribute to the heroes of Flight 93.
The Department of the Interior and our National Park Service will ensure with the families and all our partners – that we will build this shrine for the heroes of Flight 93. But our words and actions here will ring hallow unless we rededicate ourselves everyday to the inherent goodness of human kind and to the proposition that good ultimately triumphs over evil. The heroes of Flight 93 will live forever as shining examples of the human quest.
