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.
Joint Statement from Secretaries Jewell, Pritzker and Vilsack on the Drought Declaration in California

WASHINGTON, DC – Governor Brown's declaration today underscores the gravity of the historic drought conditions facing California – conditions that are likely to have significant impacts on the state's communities, economy and environment in the coming months.
We are keenly aware of the need to act quickly and collectively to address the complex challenges the drought poses, and we are directing our respective agencies to work cooperatively to target resources to help California prepare for and lessen the impacts of the drought.
This week, U.S. Department of Agriculture (USDA) designated areas in 11 states, including 27 counties in California as primary natural disaster areas due to drought. This designation makes farmers and ranchers in those counties eligible for assistance through a number of USDA programs. USDA is also working with farmers and ranchers to increase their irrigation water efficiency, protecting vulnerable soils from erosion, and improving the health of pasture and range lands. The U.S. Department of the Interior's Bureau of Reclamation is working closely with federal and state authorities to facilitate water transfers and provide operational flexibility to convey and store available water, and facilitate additional actions that can conserve and move water to critical areas. The National Oceanic and Atmospheric Administration (NOAA), part of the Department of Commerce, is providing regular updates to state officials on drought conditions. This not only includes information on weather forecasts, but also information on river water levels and potential drought impacts.
And, as called for in the President's Climate Action Plan, the National Drought Resilience Partnership (NDRP) will help coordinate the federal response, working closely with the State of California, local government, agriculture and other partners. The NDRP is already helping to enhance existing efforts that federal agencies are working on with communities, businesses, farmers and ranchers to build resilience where drought is currently an issue across the country.
Today's drought declaration also serves as a reminder of the long-term need to take a comprehensive approach to tackling California's water problems. We remain committed to working with the state to provide for the sustainable management of its precious water resources.
