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.
Junior Rangers Like to Move it, Move it: National Parks Reward Physical Activity

WASHINGTON – “Let's Move Outside, Junior Rangers!” is First Lady Michelle Obama's call to kids across the country. Today, 16 national parks – for a total of 36 nationwide – launch Let's Move Outside Junior Ranger. National Park Junior Rangers will not only have fun and get exercise but also receive an extra reward for working up a sweat. So far this summer, thousands of kids have earned the title while discovering that exercise doesn't equal drudgery.
Young people who complete a physical activity in pursuit of their Junior Ranger badge receive a sticker that designates them as a Let's Move Outside Junior Ranger. The activities range from adventures like snorkeling or kayaking at Assateague National Seashore and hiking and camping at Colorado National Monument to swimming at Boston Harbor Islands National Recreation Area and canoeing in a 26-foot Norse canoe at Voyageurs National Park.
“The Let's Move Outside program in our national parks provides a wonderful way for parents to help their children gain a passion for outdoor recreation while teaching them about our nation's beautiful lands, our rich cultural heritage and our storied past,” said Secretary of the Interior Ken Salazar.
The program engages young people in educational programs and self-guided exploration on America's public lands and waters. The activities promise to be fun, healthy and family friendly.
“Young people inspire us; we want to help them be vigorous and curious for life. It starts with family fun. National parks are amazing places where exercise is disguised as adventure, and we sneak in some learning too,” National Park Service Director Jon Jarvis said.
By summer's end, 50 national parks will offer Let's Move Outside Junior Ranger. Before heading out, visit www.letsmove.gov/letsmoveoutside.php for more information about activities and participating parks. This website hub will link families to the great outdoors and give tips and ideas on how to best plan and enjoy an active visit.
Throughout the summer, Let's Move Outside programs and events will be held in conjunction with schools, community groups, and other partners.
Let's Move Outside, led by the Department of the Interior and the Department of Agriculture, provides tools and information to parents to make it easy to enjoy the outdoors and be active. It is part of First Lady Michelle Obama's nationwide campaign to end childhood obesity within a generation.
