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.

WASHINGTON, D.C.—On Monday, April 16, Assistant Secretary of the Interior - Water and Science Anne Castle is expected to release a progress report on strategies to develop new U.S. hydropower generation at the National Hydropower Association Conference at the Capital Hilton.
The report highlights the collaborative work of the Department of the Interior, the Department of the Army, and the Department of Energy to implement a Memorandum of Understanding (MOU) among the agencies signed in March 2010 to advance development of clean, reliable, cost-effective and sustainable hydropower generation as part of President Obama's comprehensive energy strategy.
The two-year progress report details accomplishments toward achieving 13 high-level goals named in the MOU and 17 specific action items for helping to meet those goals. Collaboration and partnerships with other federal agencies, the hydropower industry, the research community, and numerous stakeholders, have helped these agencies succeed in their efforts.
