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 Launches New Resources for Open Government
Office of the Secretary
Last edited 4/25/2016
Washington, D.C. – Continuing his pledge for an open and transparent department, US Secretary of the Interior Ken Salazar today announced that the department will be launching two new resources to allow the public to view government data about America's hydropower resources on a monthly basis and data about wildland fires from the National Interagency Fire Center (NIFC) on-line.
“The Department of the Interior is committed to the success of the President's Open Government Initiative and transparency sites like Data.gov,” said Secretary Salazar. “Interior has played a key role in the development, on-going management, and evolution of Data.gov and will continue to do so.”
Interior is the second largest contributor in the Federal government to the overall number of datasets and tools accessible through Data.gov.
For the first time, the Department of the Interior is making key government data about America's hydropower resources available on a monthly basis. These data provide more detailed and timely information about the amount of raw energy generated through hydropower which helps industry, academic researchers, and government work together to develop informed strategies for sustaining a dynamic and independent energy future for all Americans. This level of analysis can be used to predict future power needs and the energy needed to meet those needs, as well as identify locations for future wind, solar, and other green energy development.
In addition to the hydropower data, the Department's Bureau of Reclamation is taking additional steps to be more open and accessible including, featuring highly requested information on the main page of its website, www.usbr.gov, and utilizing new communication channels like Twitter, Facebook, and YouTube.
Secondly, the Department of the Interior is making data about wildland fires from the National Interagency Fire Center (NIFC) available on-line. NIFC, located in Boise, Idaho, is an interagency facility that provides a national focus for the planning, coordination, and execution of a common wildland firefighting mission among the Department of the Interior land managing bureaus, the USDA Forest Service, and state, local, and tribal partners. The interagency dataset provides a statistical summary of wildland fires dating back to 1960. Access to information about wildland fires will enable the public, industry, academia, and government to work together to develop and execute informed strategies for better protecting all Americans from wildland fires.
