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.
Section 508 Compliance Evaluation of Solicitations - Suggested Assessment Criteria
All solicitations are first assessed to determine if they include electronic and information technologies (E&IT). For those solicitations that do include E&IT-related deliverables (products, labor hours, or information content), all available documents are reviewed to see if Section 508 requirements or other accessibility factors are addressed in these documents. The solicitation is then scored as follows:
1. If no mention of Section 508 is found, the solicitation is scored as "red".
2. Solicitations that mention Section 508 requirements apply generally to product, labor hour or information content deliverables are scored as yellow.
3. When broad sections and/or specific provisions of the Access Board Standards are included, the solicitation is scored as green. Solicitations that claim a Section 508 exception are also scored as green if the documentation provides a coherent rationale for the exception.
*Note -Any applicable exceptions are not assumed. While these are rare, the possibility exists that some solicitations marked red have valid exceptions. Solicitations that included documented exceptions were scored green.
Although not specifically required, including any applicable exceptions in solicitations is a best practice that shows that the 508 Standards were considered by the requiring official. Resources: the Buy Accessible Wizard at www.buyaccessible.gov and the Buy Accessible Glossary found at that site can be used as references when preparing and reviewing solicitations. General Section 508 information is always available at www.Section508.gov. The Access Board technical standards can be found: http://www.access-board.gov/sec508/standards.htm.
