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.

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.

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 Moves to Place Everglades National Park Back on List of World Heritage Sites in Danger
Last edited 4/25/2016
WASHINGTON, D.C. – Secretary of the Interior Ken Salazar today announced he is taking steps to have Everglades National Park added again to the List of World Heritage Sites in Danger by the United Nation's World Heritage Committee.
The Everglades was hastily removed from the list in 2007 at the request of the previous Administration without adequate consultations with the National Park Service, the state of Florida and other stakeholders and without appropriate measures in place to evaluate the progress of on-going efforts to restore the South Florida ecosystem, Salazar said.
“The Everglades remains one of our world's most treasured – and most threatened – places,” Salazar said at a meeting of the South Florida Ecosystem Restoration Task Force in the department's Sydney Yates Auditorium. “The federal government must once again stand up and meet its responsibilities to Everglades restoration so that one day, when we achieve restoration, we can remove the park from the list of sites that in danger. President Obama has already made a major commitment to Everglades restoration in the budget and through the Recovery Act; we will stay focused on this high priority for our nation and the world.”
President Obama has increased federal support for Everglades restoration, the largest watershed restoration project in history.
The Omnibus Appropriation Act for fiscal year 2009, signed by the President early this year, provides a total of $241 million for Everglades' projects, including $118 million from the Department of the Interior and $123 million from the U.S. Army Corps of Engineers.
In addition, the American Recovery and Reinvestment Act, also enacted earlier this year, provided $119.2 million in stimulus funding for Everglades work, including $18.6 million for Interior agencies and $100.6 million from the Army Corps of Engineers.
President Obama's budget request for 2010 would provide $278 million for Everglades' restoration, including $64 million from Interior and $214 million from the Corps. The 2010 budget for Everglades is $37 million above the 2009 enacted level.
“With the President's strong commitment to restoration, there is hope for a new day in the Everglades,” Salazar said. “We will work with other countries to relist the park at the earliest possible time and develop criteria by which we will be able to determine when that day has arrived and the park can be legitimately removed from the danger list.”
The 21-nation World Heritage Committee oversees the list of World Heritage Sites that are of significant cultural or natural importance to the common heritage of humanity. Sites that are deemed to be in jeopardy are placed on the danger list.
The committee currently is meeting in Seville, Spain. While it may be too late to formally get the Everglades relisted at this meeting, Salazar directed the National Park Service representatives attending to initial discussions with other delegates.
In 1993, the park was placed on the List of World Heritage in Danger in 1993 after Hurricane Andrew, based on concerns regarding the deterioration of the park's ecological integrity. The list is intended to focus attention and, thereby, resources of the international community and encourage action to address those threats, primarily by the concerned.
