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.

WASHINGTON – Marking the launch of the Obama Administration's America's Great Outdoors initiative as well as National Park Week, Secretary of the Interior Ken Salazar joined Postmaster General John Potter to release a new book celebrating the history of our national parks and featuring the postage stamps that have been issued over time to commemorate them.
The new book, The Grandest Things: Our National Parks in Words, Images, and Stamps, was produced by the U.S. Postal Service and the National Park Service.
Salazar said the new book underscored President Obama's Great Outdoors Initiative inaugurated earlier this month at the White House Conference on America's Great Outdoors. The president signed a Presidential Memorandum to promote and support innovative community-level efforts to conserve outdoor spaces and to reconnect Americans to the outdoors.
“I can think of no better way to help kick off the President's Great Outdoors Initiative and celebrate National Parks Week than to make available a book that combines two of America's great passions: our love of beautiful and historic places and our enthusiasm for telling our nation's story through our postage stamps,” Salazar said. “I hope that all Americans will be inspired to visit our parks and especially to take their children to see these wonderful places that lift our spirits and connect us to the natural world and our nation's history.”
"Through the stamp program, the Postal Service has always recognized the importance of our national parks," Potter said. "And in recent decades, we've recognized the need to treat our entire natural environment with the same measure of care and respect. We have an Office of Sustainability that is dedicated to this purpose. Two days from today, it will lead us in the celebration of the 40th anniversary of Earth Day."
The 116-page book tells the fascinating story of America's national parks through stamps and other memorabilia. It includes a visual tour of more than 75 parks and monuments. It also has a special stamp collecting section and comes with nine stamps with mounts, including the 8-cent 1972 Old Faithful/Yellowstone stamp. The book's retail price is $49.95.
Salazar and Potter also participated in the First Day of Issue ceremony for the Scenic American Landscapes post card set that features breathtaking sights from national parks.
Both the book and the postcards will be sold by national park bookstores and philatelic catalogs and websites..
