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.
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 Breaks Ground at Red Bluff Diversion Project Using Stimulus Funds to Help Central Valley

RED BLUFF, CALIF.— Secretary of the Interior Ken Salazar and Bureau of Reclamation Commissioner Mike Connor broke ground today at the Red Bluff Diversion Dam on Diamond Avenue as part of the largest Department of the Interior economic stimulus project in the nation. The ground breaking marks the beginning of construction of the Fish Passage Improvement Project at the Red Bluff Diversion Dam, a $5.25 million cooperative agreement that is part of the $109 million going to Red Bluff under the President's American Recovery and Reinvestment Act (ARRA).
“Through the use of economic stimulus funds, we are protecting the region's farming economy and jobs while helping to provide safe passage for fish,” Secretary Salazar said when announcing the award in July 2009. “This is a win-win project for both people and the environment and represents a vital component of the Obama Administration's effort to help the people of the Central Valley and other areas in California.”
“This project represents almost 40 years of efforts by many entities to find a balanced solution that improves fish passage and sustains the reliability of agricultural water deliveries,” Commissioner Connor said today. Construction is authorized as part of the Central Valley Project Improvement Act.
The Red Bluff Diversion Dam's gates are lowered to form Lake Red Bluff, which enables the gravity diversion of water from the Sacramento River into the Tehama-Colusa and Corning Canals to irrigate 150,000 acres of high-value cropland, more than half of which are planted in permanent orchards. However, when lowered to provide irrigation water, the gates block threatened and endangered salmon, steelhead and green sturgeon, as well as other fish species, from reaching their spawning grounds.
Reclamation's partner, the Tehama-Colusa Canal Authority (TCCA), received the $5.25 million in ARRA funds to construct an interim screened pumping plant to deliver irrigation water while the gates are raised, thus providing unimpeded fish passage. A construction contract for the bridge and siphon was awarded in December for $21.45 million and a supply contract for pumps and motors was awarded in January for $6.96 million. An additional $76.2 million in ARRA funds will be provided at a later date to construct a permanent pumping plant.
The Project will be completed in multi-phases by Reclamation, TCCA, and the State of California. The total Project cost is estimated at $230 million and is being paid for partially by the $109 million in ARRA money. Construction of the Project is expected to begin in summer 2010 and be completed in 2012.
JOBS: The Council on Economic Advisors estimates that 1,200 jobs will be created by the Project. Other indirect economic benefits of the Project include the preservation of up to 10,000 jobs in the region.
