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.
National Park Service to Release Final National Mall Plan/Final Environmental Impact Statement to Public
Last edited 4/25/2016
Washington, D.C. – With the help of community input, the National Park Service has completed a long-term vision for restoring the beauty and ensuring the sustainability of America's front yard, the National Mall. The National Park Service announced the availability of the Final National Mall Plan/Final Environmental Impact Statement (FMNP/FEIS) through a notice in the Federal Register on Tuesday, July 13th, 2010.
“The National Mall is where we celebrate the inauguration of our President, the birth of our nation, and the rights of all Americans to peacefully gather and speak their minds,” said Interior Secretary Ken Salazar. “It is also a place where we come to learn about our country, our leaders, and the events that tested us and made us strong. This new vision honors these purposes while understanding that the Mall also serves as a premier year-round venue for outdoor recreation and fun. We appreciate the thoughtful comments and active participation from so many citizens who made this plan possible.”
The planning process has involved 20 federal and local agencies, 23 days of workshops, 12 public meetings and tours, over 30,000 written comments, and presentations to dozens of community organizations and stakeholders.
Key elements of the National Mall plan include the need for:
Flexible, multi-purpose venues with appropriate backdrops and utility connections for stages, tents, and other activities.
Surfaces for jogging and walking, separate bicycle lanes, improved fields for softball, soccer, kickball, and other sports, improved conditions for passive recreation like picnicking, and locating restrooms convenient to recreation.
Improvements to general condition and appearance, additional services such as restrooms, water, information, and refreshments, spaces for cultural activities, and for capturing iconic photographic images.
Highest standards of accessibility and universal design with conveniently located seating and facilities.
Areas where groups can regroup, find shelter, sit, or gather for education or eating without impacting general visitation, and enhanced tour bus drop-off and parking.
Highest standards of recycling and waste management, design for maintenance and efficiency, use special skills teams (turf and irrigation, water features, events management), model sustainable approaches (maximize LEED rating and Sustainable Sites Initiative); improve operational access to all areas; reduce use of potable water; improve monitoring and adaptive management.
