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.
Departments of the Interior, Homeland Security Announce $6.8 Million in Conservation Projects
Office of the Secretary
Projects to Benefit Environment on the Southwest Border
Last edited 4/25/2016
Washington, DC – The U.S. Department of the Interior and U.S. Customs and Border Protection have completed the first InterAgency Agreement under the 2009 Memorandum of Agreement to fund environmental mitigation projects that will benefit several species of fish and wildlife affected by border security projects in the Southwest. Signed September 28, the agreement will fund $6.8 million in projects and represents the first of a series of efforts designed to mitigate impacts from the construction of fencing and other security measures along the U.S. Border with Mexico.
“CBP is committed to protecting our country's natural resources and wildlife while performing our security mission,” said CBP Deputy Commissioner, David Aguilar. “CBP is responsible for sound environmental stewardship and energy conservation as an integral part of their mission activities.”
“The projects we are announcing today are, in effect, part of a down payment on mitigating the impact on wildlife and its habitat from the on-going effort to secure our southern border,” Assistant Secretary Rhea Suh said. “In the future, we will continue to work with U.S. Customs and Border Protection to fund new projects that ensure threatened and endangered species and other wildlife along the border are conserved and the fragile ecosystems they depend upon are protected.”
The initial mitigation projects include funding to restore habitat for lesser long-nosed bats in Organ Pipe Cactus National Monument, Arizona; re-establish the Aplomado falcon in New Mexico; install a fish barrier at San Bernardino National Wildlife Refuge, Arizona to preclude competition with invasive species; study movement of bighorn sheep in California; survey and monitor jaguars and their habitat in Arizona.
Customs and Border Protection is funding these projects under a 2009 Memorandum of Agreement between CBP and the Department of the Interior for mitigation of unavoidable impacts to natural and cultural resources due to construction of border security infrastructure. Under this agreement, CBP will fund DOI up to $50 million over the next few years for mitigation needs.
Over the past three years, CBP has constructed about 670 miles of fence along the southwest border as an integral part of the nation's strategy to improve border security. CBP has committed to responsible environmental stewardship throughout the life-cycle of the tactical infrastructure, from construction through operations and maintenance.
The First Mitigation Projects:
Sasabe Biological Opinion
Organ Pipe Cactus NM Biological Opinion
San Bernardino Valley Mitigation
Rio Yaqui Fish Studies
Peninsular Bighorn Sheep Study
Coronado NM Agave Restoration
Northern Aplomado Falcon Reintroduction and Habitat Restoration
Border-wide Bat Conservation
U.S. Customs and Border Protection is the unified border agency within the U.S. Department of Homeland Security charged with the management, control and protection of U.S. borders at and between official ports of entry. CBP is charged with keeping terrorists and terrorist weapons out of the United States while enforcing hundreds of U.S. laws.
