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.

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.
AMERICA'S GREAT OUTDOORS:Secretary Salazar, Governor O'Malley to Host Ceremony Designating New River Trails in Five States
Trails Connect to Captain John Smith Chesapeake National Historic Trail

ANNAPOLIS, Md. – On Wednesday, May 16, Secretary of the Interior Ken Salazar, Maryland Governor Martin O'Malley, National Park Service Director Jon Jarvis and other state, local, and tribal leaders and representatives of the conservation community will participate in a ceremony to designate four connecting river trails in five states as historic components of the existing Captain John Smith Chesapeake National Historic Trail, which was established in 2006. The ceremony is open to the public.
The designation is part of President Obama's America's Great Outdoors initiative to establish a community-based, 21st century agenda for conservation of natural and historical resources, recreation, and reconnecting Americans to the outdoors. A major component of this effort includes increasing access to water-based outdoor recreation, encouraging community connections to cultural resources, and promoting tourism that fuels local economies.
The Secretarial designations will recognize the significance of the four rivers – the Susquehanna, Chester, Upper Nanticoke and Upper James Rivers – to 17th century Native American cultures and Indian trade routes. The Captain John Smith Chesapeake National Historic Trail allows visitors to re-live John Smith's exploration of the Chesapeake Bay from 1607-1609, during which Smith and his crew mapped nearly 3,000 miles of the Bay and rivers and documented American Indian communities.
