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.
Salazar Outlines Broad Opportunities for Common Ground on Wilderness
Office of the Secretary
Washington, DC – In a memo to Bureau of Land Management (BLM) Director Bob Abbey, Secretary of the Interior Ken Salazar today confirmed that, pursuant to the 2011 Continuing Resolution, the BLM will not designate any lands as “Wild Lands,” and outlined how the Department will work in collaboration with Members of Congress, states, tribes, and local communities to identify public lands that may be appropriate candidates for congressional protection under the Wilderness Act.
“The protection of America's wilderness for hunting, fishing, and backcountry recreation should be a unifying issue that mobilizes us to a common purpose,” said Secretary of the Interior Ken Salazar. “We will focus our effort on building consensus around locally-supported initiatives and working with Members to advance their priorities for wilderness designations in their states and districts. Together, we can advance America's proud wilderness legacy for future generations.”
In the memo, Secretary Salazar directs Deputy Secretary David J. Hayes to work with the BLM and interested parties to develop recommendations regarding the management of public lands with wilderness characteristics.
Noting the longstanding and widespread support for the designation of wilderness areas, Salazar also directed Hayes to solicit input from members of Congress, state and local officials, tribes and federal land managers to identify BLM lands that may be appropriate candidates for Congressional protection under the Wilderness Act. Hayes will deliver a report to the Secretary and Congress regarding those areas.
In the memo, Salazar also confirmed that BLM must continue to meet its responsibilities under the Federal Land Policy and Management Act of 1976 (FLPMA), including the requirement that it maintain inventories of the public lands, their resources and other values that it manages.
The BLM currently manages 221 Wilderness Areas designated by Congress and 545 Wilderness Study Areas, comprising approximately 8.8 percent of the nearly 245 million acres managed by the BLM.
In December, 2010, Secretary Salazar issued Secretarial Order 3310, directing the BLM to use the public resource management planning process to gather public input and designate certain lands with wilderness characteristics as “Wild Lands.” On April 14, 2011, Congress passed the Department of Defense and Full-Year Continuing Appropriations Act of 2011, which includes a provision that prohibits the use of appropriated funds to implement, administer, or enforce Secretarial Order 3310 in fiscal year 2011.
