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.
WASHINGTON — Secretary of the Interior Sally Jewell has appointed a new Chair and Vice Chair and 14 new and continuing members to the National Geospatial Advisory Committee (NGAC), which provides recommendations to the Federal Geographic Data Committee (FGDC), the interagency executive group responsible for providing leadership and direction in federal geospatial programs.
Julie Sweetkind-Singer, the new NGAC Chair, is a leader in the geospatial library and information management community, serving as the Assistant Director of Geospatial, Cartographic and Scientific Data; and Head Librarian of the Branner Earth Sciences Library and Map Collections at Stanford University. Sweetkind-Singer has served as NGAC Vice-Chair for the past year.
Keith Masback, the new vice-chair, serves as the Chief Executive Officer of the U.S. Geospatial Intelligence Foundation. Before serving in this role, he was an officer in the U.S. Army and a senior executive in the National Geospatial-Intelligence Agency.
"We are honored to have these accomplished geospatial professionals as leaders and members of the National Geospatial Advisory Committee,” said Jennifer Gimbel, Principal Deputy Assistant Secretary of the Interior for Water and Science, who serves as Chair of the FGDC Steering Committee. “The NGAC has been a valuable resource and an excellent partner for the Federal geospatial community, and has provided thoughtful advice and recommendations on a wide range of geospatial policy and management issues. Geospatial data and technology are essential for Federal agencies and we look forward to continuing our collaboration with this distinguished set of leaders.”
The NGAC includes up to 30 members, selected to achieve a balanced representation of the varied interests associated with geospatial programs and technology. NGAC members are appointed to serve staggered terms on the committee. The appointees to three-year terms on the NGAC are:
Mr. David Alexander, Department of Homeland Security Mr. Frank Avila, National Geospatial-Intelligence Agency Dr. Sarah Battersby, Tableau Software Mr. Talbot Brooks, Delta State University (reappointed to a second term) Mr. Matt Gentile, Deloitte Financial Advisory Services (reappointed to a second term) Mr. Frank Harjo, Muscogee (Creek) Nation (reappointed to a second term) Mr. Xavier Irias, East Bay Municipal Utility District Mr. Roger Mitchell, MDA Information Systems, Inc.

The NGAC meets three to four times per year. The public is invited to comment and make suggestions at all committee meetings, which will be announced by publication in the Federal Register at least 15 days before the meeting date. The U.S. Geological Survey, a bureau of the Department of the Interior, provides support services for the NGAC. The NGAC functions solely as an advisory body.
The NGAC was created under the Federal Advisory Committee Act, enacted by Congress in 1972 to ensure that advice rendered to the executive branch by advisory committees, task forces, boards, and commissions formed by Congress and the President, be both objective and accessible to the public. The Act formalized a process for establishing, operating, overseeing, and terminating these advisory bodies.
