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.
AMERICA'S GREAT OUTDOOORS: Reversing Decades of Decline, the Number of Hunters and Anglers is on the Rise
Office of the Secretary
Salazar: Survey Delivers ‘Great News for America's Economy and Conservation Heritage'
MILWAUKEE, WI – Highlighting the reversal of decades of declining numbers, Secretary of the Interior Ken Salazar today announced the results of a comprehensive national survey of outdoor recreation showing a significant increase in hunters and a double-digit increase in anglers over the past five years.
“Seeing more people fishing, hunting, and getting outdoors is great news for America's economy and conservation heritage,” said Salazar. “Outdoor recreation and tourism are huge economic engines for local communities and the country, so it is vital that we continue to support policies and investments that help Americans get outside, learn to fish, or go hunting. That is why, through President Obama's America's Great Outdoors initiative, we have been focused on helping Americans rediscover the joys of casting a line, passing along family hunting traditions, and protecting the places they love.”
The U.S. Fish and Wildlife Service's 2011 National Survey of Fishing, Hunting, and Wildlife-Associated Recreation found that hunters nationwide increased by 9 percent while anglers grew by 11 percent. Nearly 38 percent of all Americans participated in wildlife-related recreation in 2011, an increase of 2.6 million participants from the previous survey in 2006. They spent $145 billion on related gear, trips and other purchases, such as licenses, tags and land leasing and ownership, representing 1 percent of the nation's gross domestic product.
“The Fish and Wildlife Service is dedicated to connecting people and families with nature,” said Fish and Wildlife Service Director Dan Ashe. “We look forward to continuing to work with the States, non-governmental organizations, and additional partners to help keep recreational fishing, hunting, and wildlife watching going strong for people across America's great outdoors.”
Other key findings include:
• In 2011, 13.7 million people, 6 percent of the U.S. population 16 years old and older, went hunting. They spent $34.0 billion on trips, equipment, licenses, and other items in 2011, an average of $2,484 per hunter.
• More than 33 million people 16 and older fished in 2011, spending $41.8 billion on trips, equipment, licenses, and other items, an average of $1,262 per angler.
• More than 71 million people engaged in wildlife watching in 2011, spending $55.0 billion on their activities
At the request of state fish and wildlife agencies, the Fish and Wildlife Service has been conducting the national survey every five years since 1955. It is viewed as one of the nation's most important wildlife-related recreation databases and the definitive source of information concerning participation and purchases associated with hunting, fishing and other forms of wildlife-related recreation nationwide.
“State agencies, hunters and anglers are the key funders of fish and wildlife conservation through their license and gear purchases,” said Dr. Jonathan Gassett, Commissioner of the Kentucky Fish and Wildlife Resources Commission and President of the Association of Fish and Wildlife Agencies. “An increase in participation and expenditure rates means that agencies can continue to restore and improve habitat and fish and wildlife species, bring more youth into the outdoors and provide even greater access to recreational activities.”
The U.S. Census Bureau interviewed 48,627 households across the country to obtain samples of sportspersons and wildlife watchers for detailed interviews. Information was collected through computer-assisted telephone and in-person interviews.
The Survey is funded through a Multi-State Conservation Grant from the Wildlife and Sport Fish Restoration Program, which celebrates 75 years of conservation success in 2012.
The report is the first in a series that the Service will release. The next report of findings will contain State data and will be available in the coming months. In late November, the National Report with more detail participation and expenditure estimates will be available online. From December 2012 to May 2013, the 50 State reports will be released on a rolling basis.
