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.
Deputy Secretary Hayes Meets with Alaska Regional Leaders and Renewable Energy Experts
ANCHORAGE, AK – Deputy Secretary of the Interior David J. Hayes today met with senior federal and state officials in Anchorage to ensure the continuing coordination of federal responsibilities related to energy permitting in Alaska. The visit was part of President Obama's all-of-the-above energy strategy to safely and responsible expand domestic energy production and to coordinate energy development and permitting in Alaska.
“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, who serves as chair of the Interagency Working Group on Coordination of Domestic Energy Permitting in Alaska established in July by President Obama to coordinate energy development in Alaska. “While agencies across the Federal government have various responsibilities to ensure safe and responsible energy development in Alaska, it is more important than ever that federal reviews of energy projects proceed in an efficient and coordinated way, with the federal government speaking with one voice.”
As part of the Working Group's ongoing efforts to advance renewable energy development in Alaska, Hayes met with Alaska renewable energy experts to discuss ways to promote small-scale wind energy solutions for rural Alaskan villages. The meeting was one in a series of recent initiatives by state and federal policy-makers to address the energy challenges facing rural Alaskans—particularly in off-the-grid, rural Alaska villages—and build upon the success of Alaska's growing renewable energy sector.
“Access to reliable, affordable energy remains a significant problem in rural Alaska,” added Hayes. “One potential solution can be found in Alaska's abundant wind resources. With a number of successful wind energy projects underway across the state, from Kodiak to Kotzebue, the time is ripe to apply lessons learned and support similar projects in isolated but renewable energy-rich villages in Alaska. We look forward to working closely with the state, rural energy providers, NGOs and others who have already devoted significant time and resources to address these challenges.”
Meeting participants included state leaders in Alaska renewable energy, including utilities, state and federal officials, Alaska Native organizations, members of the academic community, non-governmental organizations and industry.
