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.
Geospatial Site Provides Ongoing Awareness of Natural Hazards
Office of the Secretary
IGEMS offers integrated maps allowing monitoring, analysis as events occur

WASHINGTON – A new Interior Department website offers the public as well as federal, state and local emergency management communities online maps containing the latest available information on earthquakes, earthquake shakemaps, streamflow data and floods, volcanoes and wildfires, as well as information on severe weather hazards.
The Interior Geospatial Emergency Management System (IGEMS), managed by the department's Office of Emergency Management, provides ongoing awareness of natural hazards, enabling individuals to monitor and analyze natural hazard events as they occur. Information is presented in an integrated geospatial view that locates these threats with reference data, including various basemaps that can be selected by users. The system utilizes data from Interior bureaus, such as the U.S. Geological Survey as well as data provided by the National Weather Service and other authoritative sources.
“Awareness of natural hazards -- whether from geological threats such as earthquakes and volcanoes or from severe weather -- help us to make prudent decisions on how much we should invest in preparedness and planning for such events,” said Laurence Broun, Interior's Director of Emergency Management. “Our Interior Operations Center and other government facilities have immediate access to natural hazard information. Using the power of the internet, it is now possible for us to share a picture of current natural hazards with the public, integrating our own data with that of other government agencies.”
IGEMS is the next generation replacement for the Natural Hazards Support System that had been in operation since 2003, supporting a significant customer base that registered more than 8 million hits a month. That system was one of the first public applications to provide an integrated approach in incorporating a wide range of hazards into a dynamic mapping environment. Since IGEMS uses the latest software and technology, it provides functionality beyond that of the earlier system, including support for mobile devices such as tablets and smartphones.
“The emergency management and preparedness communities have a long history of collaboration in developing and sharing critical data and maps, which enables us to work together to protect property and lives,” said Jerry Johnston, Interior's Chief Geospatial Officer. “With the advancement of web mapping technology, the public expects to also be able to quickly and easily access this information, and IGEMS is a great tool that allows everyone to share this common view.”
IGEMS, located at igems.doi.gov, is managed by the Geosciences and Environmental Change Science Center, U.S. Geological Survey, under an agreement with Interior's Office of Emergency Management. Comments on the website, including recommendations for future data enhancements, can be directed to the systems manager, Jill Cress, at email@example.com. Cress developed the original Natural Hazards Support System and has worked closely with partners in numerous government agencies to develop reliable, authoritative sources of data for timely display of natural hazard information.
