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.
Interior Issues Draft Overview Report on Klamath Dam Removal Studies
Draft overview captures potential economic, environmental opportunities; Public comment on draft sought by February 5, 2012
Washington, DC – The Interior Department today published a draft report summarizing two years of scientific and technical studies conducted to help inform the Secretary of the Interior on a forthcoming decision on whether to remove four hydroelectric dams on the Klamath River, per the Klamath Hydroelectric Settlement Agreement (KHSA) of 2010. The comprehensive draft report, entitled Klamath Dam Removal Overview Report for the Secretary of the Interior: an Assessment of Science and Technical Information (Overview Report), and each individual study conducted on the environmental and economic impacts of the potential dam removal, are available at www.KlamathRestoration.gov.
The draft report presents in plain language a summary of dozens of peer-reviewed reports that have been prepared by the federal government and made public as part of the effort to fill important data gaps prior to a Secretarial Determination. Many of the findings – in disciplines including economics, engineering, biology, water quality, recreation and real estate – were first published in September.
“The science and analyses presented in these reports are vital to making an informed and sound decision on the Klamath River dam removal,” said Secretary of the Interior Ken Salazar. “As we work toward strengthening the health and economic prosperity of all that depends on the Klamath – including our watersheds, fisheries, and forests - I encourage members of the public to offer their input on this draft overview report and perspectives on the opportunity that lies ahead.”
The Interior Department today also released an updated Economics and Tribal Summary Technical Report and the Klamath River Basin Restoration Nonuse Value Survey Final Report. The Economics and Tribal Summary Report provides an assessment of the economic benefits and costs of dam removal. The Nonuse Value Survey Final Report provides estimates of one important component of the economic benefits, nonuse values.
The economic reports analyzed in the draft Overview Report find that dam removal and implementation of the related watershed-wide restoration program provide an opportunity to bring significant additional jobs to the region and strengthen local economies in the Klamath Basin for reasons that include improved fish populations; additional recreational and commercial fishing opportunities; and increased agricultural output due to more certainty in water deliveries.
A summary of the key conclusions from the scientific and technical reports is available here.
As part of its commitment to openness, transparency and scientific integrity, the Interior Department is arranging for a scientific peer review of the draft Overview Report by a six-member independent panel. In addition, the Department is encouraging the public to review and offer technical comments on the draft report for the peer reviewers to consider during their deliberations.
The peer reviewers were selected based on their expertise to review the technical information contained in the draft report, including engineering, fisheries biology, stream restoration, geomorphology, stream ecology, hydrology, water quality, natural resource economics, and anthropology/tribal history. Atkins North America, a firm with a specialty in overseeing scientific peer reviews, will facilitate the deliberations of the peer review panel and will assist them in the preparation of their report of peer review comments.
The final Overview Report, and the dozens of reports it summarizes, along with the final Environmental Impact Statement/Environmental Impact Report on Klamath River dam removal, will help inform the Secretarial Determination, which is expected later this spring.
The public comment period on the Klamath Overview Report is open from January 24 through February 5, 2012. Comments received after this date will not be considered by the peer reviewers. Public comments should be emailed to: firstname.lastname@example.org, or mailed to:
