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.

GETTYSBURG, Pa. -- Secretary of the Interior Sally Jewell today offered keynote remarks at the ceremony honoring the 150th anniversary of President Lincoln's Gettysburg Address. The ceremony at Gettysburg National Military Park was attended by National Park Service Director Jonathan B. Jarvis, Gettysburg Superintendent Bob Kirby, Governor Tom Corbett, U.S. Supreme Court Justice Antonin Scalia, U.S. Senators Bob Casey and Pat Toomey, U.S. Representative Scott Perry, Pulitzer Prize-winning historian James McPherson, and many NPS employees, volunteers and community members.
The observance took place in Gettysburg's Soldiers' National Cemetery and featured a reading of the Gettysburg Address by Lincoln portrayer James Getty. U.S. Citizenship and Immigration Services also administered the Oath of Allegiance to sixteen new American citizens following the ceremony.
In the spirit of President Lincoln's historic address, Secretary Jewell limited her formal remarks to 272 words.
Secretary Jewell's remarks, as prepared for delivery:
One hundred fifty years ago, Abraham Lincoln said, “the world will little note, nor long remember what we say here.” He was wrong. Just as the battle that raged on these fields stands at the vortex of American history, Lincoln's words stand at the vortex of our national consciousness.
Hearing them, we are reminded of the sacrifice of so many for freedom. We are likewise reminded of our long journey, still on-going, to fulfill the fundamental proposition that indeed all men and women are created equal and deserve the full benefit of this freedom that has been purchased at such great price.
The steps on this journey are marked by eloquence. The patriot who regretted he had but one life to give for his country. The president who affirmed our resolve on a day that will live in infamy. The courageous woman whose simple “No” on an Alabama bus gave birth to choruses of “We Shall Overcome.” The passenger above another Pennsylvania field, who declared “Let's Roll,” giving voice to a nation battered by terrorism.
But no words are greater than those spoken here by a simple man, born in a log cabin, who not only saved the American union but also came to symbolize its greatest virtues of humility, honesty, and decency.
His words, chiseled on the walls of his memorial, are likewise chiseled on our hearts. They tell us what it means to be an American. They call us to unfinished work, not just to win a war, but to continue to perfect our nation and a government that is truly “of the people, by the people, for the people.”
