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.
Secretary Jewell Announces Nomination of San Antonio Missions as World Heritage Site
Office of the Secretary
Would Join U.S. Sites Such as Yellowstone, the Grand Canyon, and the Statue of Liberty

WASHINGTON, DC – Secretary of the Interior Sally Jewell today announced that the United States is nominating the San Antonio Missions, consisting of most of San Antonio Missions National Historical Park as well as the Alamo, for inclusion on the World Heritage List, which recognizes the most significant cultural and natural sites on the planet.
“World Heritage Sites represent an incredible opportunity for the United States to tell the world the whole story of America and the remarkable diversity of our people and beauty of our land,” Jewell said. “The San Antonio Missions represents a vital part of our nation's Latino heritage and the contributions of Latinos to the building of our country.”
Jewell credited former Secretary Ken Salazar, who visited San Antonio Missions in July 2012 to announce the department's intention to move forward with the nomination, for playing a key role in making it possible.
This nomination will be considered for inscription on the World Heritage List by the UNESCO World Heritage Committee in the summer of 2015. If approved by the World Heritage Committee, it would join the 21 sites in the U.S. already inscribed on the World Heritage List, which is listed below.
The UNESCO World Heritage List falls under the auspices of the World Heritage Convention, of which the United States was the prime architect. It is an international treaty for natural site conservation and cultural site preservation proposed by President Richard M. Nixon in 1972; the U.S. was the first nation to ratify it.
There are currently 981 sites in 160 of the 190 signatory countries. The list includes such iconic places as the Taj Mahal, Stonehenge and the Great Barrier Reef, as well as Yellowstone National Park, Grand Canyon National Park and the Statue of Liberty National Monument in the United States.
“World Heritage Sites draw visitors from around the world, providing not only prestige to local communities but also a boost to their economies,” Jewell noted.
The Department of the Interior is undertaking the nomination with the full cooperation and written support of all the property owners within the boundaries of the nominated area, including the National Park Service, the State of Texas, the Catholic Archdiocese of San Antonio, Bexar County, the City of San Antonio, the San Antonio River Authority, the Espada Ditch Company, the San Juan Ditch Water Supply Corporation, and Los Compadres de San Antonio Missions National Historical Park.
These owners, together with partner organizations, cooperated to prepare the nomination in consultation with the National Park Service's Office of International Affairs, the principal technical agency for the U.S. Government's participation in the Convention.
The nomination will be submitted through the U.S. Department of State to the offices of the World Heritage Centre in Paris, France. After reviews by World Heritage Centre staff and by the International Council for Monuments and Sites (ICOMOS), it will be considered for inscription on the World Heritage List by the World Heritage Committee, which is a rotating body of 21 nations elected from among the signatories of the World Heritage Convention.
Inscription as a World Heritage Site does not impose any legal restrictions on property owners or neighbors of sites, nor does it give the United Nations any management authority or ownership rights in U.S. World Heritage Sites, which continue to be subject only to existing federal and local laws. The agreement of the property owner is required by U.S. law in order for a site in this country to be nominated to the World Heritage List.
As previously announced, the Department of the Interior plans to revise the candidate list, or Tentative List of potential future U.S. World Heritage nominations, by 2016. Interested parties may suggest properties for consideration at any time.

“The San Antonio Missions”
The San Antonio Missions are nominated under World Heritage cultural criteria (ii), (iii) and (iv) as the most complete and most intact example of the Spanish Crown's efforts to colonize, evangelize, and defend the northern frontier of New Spain during the period when Spain controlled the largest empire in the world. Situated along a 7.7-mile stretch of the San Antonio River, these five Spanish colonial mission complexes were built in the early eighteenth century. The missions' more than fifty standing structures, archaeological resources, and landscape features include labores, a rancho, residences, a grist mill, granaries, workshops, wells, lime kilns, churches, conventos, and perimeter walls for protection. The ensemble of missions includes extensive agricultural irrigation systems of acequias, dams, and an aqueduct.
The United States revised and resubmitted its World Heritage Tentative List in January of 2008; under the World Heritage Committee's Operational Guidelines, properties must be included on a country's Tentative List before they can be nominated.
There are 12 additional properties or groups of properties on the Tentative List. Of these, the “Monumental Earthworks of Poverty Point” in Louisiana was nominated last year and will be considered by the World Heritage Committee this summer; and a group of buildings designed by Frank Lloyd Wright has been authorized to prepare a nomination, which is now in development.
Decisions on the timing and sequence for future nominations will be made periodically by the Department, and will include an opportunity for public comment. More information on the World Heritage Program can be found here.
