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.
Interior Deputy Secretary Hayes Highlights Administration's Commitment to Safe and Responsible Domestic Energy Development in Alaska
Launches Coordinated Renewable Energy Initiatives in Alaska as part of Interagency Working Group; NPR-A Lease Sale Set for December
ANCHORAGE—Wrapping up a trip to Alaska, Department of the Interior Deputy Secretary David J. Hayes today highlighted several initiatives underway to spur development of our nation's domestic energy resources, including federal task force efforts to help harness Alaska's renewable and conventional energy resources, and an oil and gas lease sale for the National Petroleum Reserve-Alaska (NPR-A). The initiatives are part of a series of steps President Obama announced this past spring to continue to expand safe and responsible production of our domestic resources.
“Alaska's energy resources – onshore and offshore, conventional and renewable - hold great promise and economic opportunity for the people of Alaska and across the nation,” said Deputy Secretary Hayes. “We know that a ‘one-size-fits-all' approach doesn't work when it comes to Alaska, and we will continue to pursue a balanced approach to safely and responsibly developing Alaska's energy supplies.”
Hayes was in Anchorage as chair of a high-level federal interagency working group established in July by President Obama to coordinate energy development in Alaska. During the two-day trip, Hayes participated in a series of meetings with federal, state, local, and tribal leaders, as well as conservation and energy industry stakeholders.
Hayes announced that, in recognition of Alaska's significant renewable energy potential, the cross-agency team is working to spur not only balanced conventional energy development, but has also formed a task force to encourage the development of renewable energy resources, including wind, biomass and hydropower. A task force will also focus on improving delivery of renewable energy to rural Alaskan villages.
“Across the nation we are unlocking the potential of the wind and sun to power our homes and communities,” Hayes said. “Harnessing Alaska's abundant renewable energy sources would strengthen the state's energy economy and add a critical component to Alaska's growing energy portfolio. I look forward to working with our partners across the state to make renewable energy projects in Alaska a reality.”
The State of Alaska has signaled its commitment to facilitating renewable energy development with substantial investments in individual renewable energy projects, weatherization, and energy efficiency projects. Hayes noted that the federal government can play an important role in supporting those efforts and helping the State achieve its goal of deriving half its power from renewable energy sources by 2025.
Hayes also announced that, as part of President Obama's efforts to increase safe and responsible production of our domestic oil and gas resources, the Bureau of Land Management (BLM) will hold a lease sale on Dec. 7 for approximately 3 million acres - an area larger than Rhode Island and Delaware combined - in the NPR-A. The lease sale, details of which are available in the Federal Register tomorrow, will offer 283 tracts and is coordinated with a State of Alaska sale, offering industry adjacent tracks in state and federally-managed areas.
Today's accelerated lease sale is a direct result of President Obama's announcement in May in which he directed Interior to conduct annual lease sales in the NPR-A.
The NPR-A is a 23-million-acre area on Alaska's North Slope, west of Prudhoe Bay. The U.S. Geological Survey estimates the reserve and adjacent state waters contain 896 million barrels of conventional, undiscovered technically recoverable oil and 53 trillion cubic feet of conventional, undiscovered technically recoverable non-associated gas. This will be the seventh lease sale in the reserve since 1999.
In selecting tracts to offer, the BLM considered natural resource values, resource potential, industry interest and subsistence values. Performance based stipulations and required operating procedures will be used to mitigate resource impacts, while adapting to new information and changing conditions.
