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.
Trustees Open 45-Day Comment Period on Draft Regional Restoration Plan for Natural Resources Injured by Hazardous Substances Releases in Southeast Missouri
Last edited 2/14/2017
On September 20, 2013, the federal and State natural resource trustees opened a 45-day public comment period on “Southeast Missouri Ozarks Regional Restoration Plan and Environmental Assessment.” This draft Regional Restoration Plan describes proposed alternatives for restoring natural resources and natural resource services injured by hazardous substances releases in the southeast Missouri Ozarks lead mining district.
The natural resource trustees involved in this case include:
State of Missouri, represented by Missouri Department of Natural Resources;
U.S. Department of Agriculture, represented by U.S. Forest Service; and,
U.S. Department of the Interior, represented by U.S. Fish and Wildlife Service.
The southeast Missouri Ozarks lead mining district covers multiple counties south and southwest of the City of St. Louis. The region is the largest lead production area in the U.S. Within this district are several lead mining areas that are geographically and temporally distinct:
the Big River Mine Tailings site, directly south of St. Louis, dates from the 19th century through the 1970s;
the Madison County Mine site, south of the Big River Mine Tailings site, has some of the oldest mining operations in Missouri dating from 1740; and,
the Viburnum Trend site, located farther west, began lead mining in the 1950s and remains the largest producer of lead in the U.S. today.
Mining activities -- including beneficiation, transportation and smelting -- have resulted in the release of hazardous substances, mainly heavy metals. U.S. Environmental Protection Agency has placed large portions of the district on the National Priorities List.
These hazardous substances releases have resulted in injuries to natural resources and natural resource services including large-scale ecological injury to thousands of acres of terrestrial habitat and hundreds of miles of streams. Five settlements for natural resource damages, totaling $41,178,370, were reached in 2009 as part of the larger ASARCO bankruptcy settlement agreement.
The trustees developed the draft Regional Restoration Plan to identify preferred alternatives to restore injured natural resources and to establish criteria for selecting specific projects to implement these alternatives. This draft Regional Restoration Plan selects compensatory restoration projects -- projects located away from the site of injury -- as the preferred restoration alternative. These projects will be funded using the natural resource damage settlements and selected by the trustees using a Request-for-Proposals approach.
Written comments on the draft Regional restoration Plan must be received by Missouri Department of Natural Resource by Monday, November 4, 2013.
