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 Wednesday, April 24, Secretary of the Interior Sally Jewell and U.S. General Services Administration (GSA) Acting Administrator Dan Tangherlini will announce that Interior will be the first federal agency to update its federal fleet with hybrid vehicles as part of GSA's new initiative to replace an aging federal fleet with hybrid vehicles.
Interior and GSA will partner to replace up to 300 gasoline and alternative fueled vehicles with hybrids. This will replace nearly a third of the vehicles owned by the Department under consideration.
“We are excited to be the first to partner with GSA on this important initiative to make our vehicles more fuel efficient,” said Jewell. “We will target replacement where it makes the most sense and has the greatest return on investment. This is a simply a good business decision that will benefit not only our bottom line, but reduce our carbon emissions as well.”
“Providing a hybrid federal fleet is an essential part of GSA's commitment to making government agencies as efficient and effective as possible,” said Tangherlini. “At a time when government needs to make every tax dollar count, GSA is committed to creating more energy efficiency and cost-saving opportunities like the fleet consolidation program that make government smarter and reduce our environmental footprint.”
GSA on Monday announced its Fleet Consolidation program to give federal agencies the opportunity to replace their aging fleets with hybrid vehicles. Through this initiative GSA expects to expand their number of hybrid vehicles by up to 10,000. GSA will fund the total incremental cost to replace consolidated vehicles with new hybrid sedans.
Jewell and Tangherlini will make the announcement in Washington D.C.'s Rawlins Park where OPM, GSA and DOI are hosting an Earth Day event with recycling opportunities and fuel efficient car demonstrations.
