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.

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.

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 350,000 Acre Feet of Additional Water Availability to Central Valley Project Water Users
Expedited Water Rescheduling, Exchanges and Transfers Will Help Growers Plan for 2010

WASHINGTON, D.C. – Secretary of the Interior Ken Salazar today announced additional actions to assist water users in California, particularly farmers in the West Side of the San Joaquin Valley, who have been severely impacted by three years of drought and reduced allocations of Federal Central Valley Project (CVP) water.
“The recent storms in California are welcome relief for farmers, water users, and watersheds that have been hit hard by three years of drought,” said Secretary Salazar, “but we are not out of the woods yet. We must keep all hands on deck to stretch water supplies, move water to where it is needed most, provide certainty for growers in the year ahead, and build long-term water solutions in partnership with the State.”
To assist farmers in the short term, Secretary Salazar announced 350,000 to 400,000 acre-feet of water will be made available for West Side farmers by March 1, the beginning of the contract water year. When the Mid-Pacific Region makes its initial CVP water allocation announcement for Water Year 2010 near the end of February, the allocation will be in addition to these amounts.
This assured water supply is being provided as a result of two significant actions taken by the Bureau of Reclamation. First, Reclamation's Mid-Pacific Region issued rescheduling guidelines on July 30, 2009 – much earlier in the water year than ever before – to allow farmers to hold water over for the 2010 growing season. Second, because storms have raised precipitation numbers throughout the CVP to “average” for this time of year, the Bureau has determined that it can deliver non-CVP water currently stored in the San Luis Reservoir under Warren Act contracts and approve requests to reschedule CVP supplies from the 2009 contract year for delivery in 2010.
"The steps we are taking will help provide water users and growers critical assurances for the year ahead,” said Salazar. “The Obama Administration is committed to being a full partner with the State and stakeholders in both addressing urgent water needs and laying a foundation for California's water future.”
