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.
The National Invasive Species Council’s (NISC) high-level policy and planning activities benefit from the technical input provided by Federal agency staff, and Federal inter-agency bodies working on invasive species issues, as well as non-Federal stakeholders. The Invasive Species Advisory Committee (ISAC) is a group of non-federal experts and stakeholders established to provide advice to the Council on invasive species-related issues. ISAC’s primary duty is to “recommend plans and actions at local, tribal, state, [territorial], regional, and ecosystem-based levels to achieve the goals and objectives of the Management Plan.” ISAC members include representatives of state, territorial, tribal, and local governments, as well as academic institutions, non-governmental organizations, and the private sector.
ISAC is chartered under the Federal Advisory Committee Act (FACA) and administered according to its bylaws. ISAC typically holds two meetings per year. All meetings are open to the public, and minutes of each meeting are publicly available.
Since its creation in 1999, ISAC has provided valuable input to NISC on a wide range of Federal priorities and emerging issues. ISAC advice and other resources are available here.
Coordinated through the NISC Secretariat, ISAC is currently focused on the following topics:
Strengthening Federal/State coordination;
Strengthening Federal/Tribal coordination;
Identifying risks and opportunities for the application of emerging biotechnologies for invasive species prevention, eradication, and control;
Assessing the impacts of invasive species on infrastructure; and
Assessing the impacts of invasive species on wildlife health.
ISAC members are appointed by the Secretary of the Interior with extensive input from the other NISC members. When there is a need to fill ISAC vacancies, the NISC Secretariat publishes a call from nominations in the Federal Register. No vacancies are available at this time.
