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.

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.

WASHINGTON, D.C. – On Tuesday, July 30, Secretary of the Interior Sally Jewell will sign an historic agreement at the Department of the Interior that will guarantee water rights for the White Mountain Apache Tribe of Arizona and provide water security for the City of Phoenix and other downstream water users. The ceremony will be live-streamed to the public.
Secretary Jewell will be joined by White Mountain Apache Chairman Ronnie Lupe, Former U.S. Senator John Kyl, U.S. Representative Ann Kirkpatrick and other federal, tribal and state dignitaries.
The White Mountain Apache Reservation includes more than 1.6 million acres in the headwaters of the Salt River basin in Arizona. The agreement to be signed on Tuesday will provide funding for design and construction of a rural water delivery system on the Reservation and secure water flow for the city of Phoenix which depends on the same river basin for basic water needs. The agreement is one of four Indian water agreements authorized in the Claims Resolution Act signed by President Obama on December 8, 2010.
