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.
Secretary Salazar Announces Additional Water Releases from Upper Klamath Lake to Klamath Irrigators
Office of the Secretary

WASHINGTON, D.C.--Secretary of the Interior Ken Salazar announced today that 35,000 acre-feet of additional water may be available for release this year from Upper Klamath Lake for delivery to irrigation contractors. Current modeling estimates the additional water will be available because Upper Klamath Lake surface water elevations are higher than previously anticipated due to a cooler-than-normal spring resulting in lower evaporation rates and reduced irrigation demands above the lake and on the Klamath Project lands.
The Bureau of Reclamation's 2010 Operations Plan for the Klamath Project previously indicated that 150,000 acre-feet of water would be available for irrigation contractors; however Reclamation's modeling currently estimates that up to an additional 35,000 acre-feet could be made available during this irrigation season—for a possible total of 185,000 acre-feet. The actual amount of additional water available above the 2010 Operations Plan may change depending on conditions as the irrigation season progresses.
“This additional water is good news,” said Secretary Salazar, “but the Department of the Interior will intensify our efforts on behalf of all stakeholders because the Klamath Project is still receiving less than 50 percent of its historical average. Communication among stakeholders continues to be vital during the current drought.”
Secretary Salazar said that the Department, through its Bureau of Reclamation, will continue to work closely with irrigators, state and federal agencies, and Tribes to monitor the conditions closely with the goal being to satisfy Biological Opinion requirements, meet Tribal Trust responsibilities, and ensure that available water is used beneficially within the Klamath Project.
The irrigation districts will determine how best to use the additional water. Possible options for using the additional water include extending the irrigation season, providing water to lands not currently receiving Klamath Water and Power Agency support, or reducing the reliance on groundwater pumping.
Authorized in 1905, the Klamath Project, located in southern Oregon and Northern California, is one of the oldest projects of the Bureau of Reclamation. The Project's facilities include the Link River, Gerber, Clear Lake, and Anderson-Rose Dams as well as nearly 142,000 acres of wetlands and wildlife refuges.
