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.
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.
Salazar to Highlight Cultural and Historic Tourism in San Antonio
Will speak at US/ICOMOS Symposium; Visit San Antonio Missions
Last edited 4/27/2016
SAN ANTONIO, Texas – Today and tomorrow, Secretary of the Interior Ken Salazar will visit San Antonio to highlight the advancement of the San Antonio Franciscan Missions toward nomination to the UNESCO World Heritage List. During his visit, Secretary Salazar will discuss the importance of preserving the city's iconic cultural and historic sites to grow domestic and international travel and tourism and create jobs – part of part of Interior's ongoing efforts to capture and tell a more inclusive story of American history.
On Thursday, May 31, Secretary Salazar will deliver remarks to the 15th annual international symposium of the U.S. National Committee for ICOMOS (International Council on Monuments and Sites), celebrating the 40th anniversary of the World Heritage Convention.
On Friday, June 1, Secretary Salazar will hold a press conference at Mission Concepción to discuss the San Antonio Franciscan Missions and the progress underway toward nomination to the UNESCO (United Nations Educational, Scientific and Cultural Organization) World Heritage List.
Under the Convention, the Secretary of the Interior is charged with identifying and nominating worthy U.S. sites that display superlative cultural and/or natural attributes for designation. The San Antonio Franciscan Missions, currently on the Tentative List of Potential Future Nominations, includes four missions (San Antonio Missions National Historical Park) and the Alamo (Mission San Antonio de Valero).
The visit is part of President Obama's America's Great Outdoors initiative to establish a conservation ethic for the 21st Century and to reconnect Americans to our nation's natural, cultural, and historic heritage. The Obama administration is committed to recognizing and preserving important chapters in the nation's story that have not yet been fully told, such as the contributions of Latinos to the building of America.
The visit also builds on the Obama administration's recently-announced National Tourism and Travel Strategy, which delivered on President Obama's call in January for a national strategy to promote domestic and international travel opportunities throughout the United States.
