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.

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.
Secretary Jewell to Join Sen. Reed in Rhode Island to Highlight Economic, Recreational Value of Parks, Trails, Waterways
Will kick off National Trails Day with kayak trip down Blackstone River
CUMBERLAND, RI – On Friday, May 31, Secretary of the Interior Sally Jewell and National Park Service Director Jonathan B. Jarvis will join U.S. Senator Jack Reed at the John H. Chafee Blackstone River Valley National Heritage Corridor to highlight the economic and recreational value of national parks, national wildlife refuges, waterways and other public lands. The visit will include kayaking down the Blackstone River waterway, in advance of National Trails Day on Saturday, June 1.
Tourism and outdoor recreation are huge economic engines for local communities across the nation. In Rhode Island, the Roger Williams National Memorial had an estimated 52,000 visitors in 2012 with a $3 million economic benefit to the state. The outdoor recreation economy in the state is estimated to generate $2.4 billion in consumer spending and 24,000 direct jobs, according to a report by the Outdoor Industry Association.
Jewell, Jarvis and Reed will also meet with community leaders to discuss the Obama Administration's efforts to boost conservation, as well as progress being made to establish a new national historical park within the Blackstone River Valley to interpret the role the area played in the Industrial Revolution and provide outdoor recreational opportunities for visitors.
