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.
Salazar Statement on Shell Activities in the Arctic
Office of the Secretary
WASHINGTON – Interior Secretary Ken Salazar released the following statement today after Shell announced it would not drill into oil-bearing zones in the Arctic this year:
“The Interior Department will continue to work with Shell as it oversees the company's preparatory drilling work and other data-gathering activities in the Arctic's Chukchi and Beaufort Seas. The Department has set rigorous safety, environmental protection and emergency response standards for any exploration activities in the Arctic, and throughout this process, Shell has demonstrated a commitment to those standards. Through Shell's efforts, tremendous progress has been made and valuable lessons will be learned as the company carefully and deliberately moves forward with Arctic exploration activities. As part of President Obama's all-of-the-above energy strategy, we look forward to continuing to work with Shell to maximize the remaining opportunities this drilling season provides while doing so in a manner that expands domestic energy production, creates jobs, protects people, and safeguards our natural resources.”
