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.

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:

The Office of Management and Budget (OMB) directive, Final Information Quality Bulletin for Peer Review, dated December 15, 2004 (263 KB PDF), requires that there be a "systematic process of peer review planning" and access to a list of information products for official dissemination that will be peer reviewed as either influential scientific information or highly influential scientific assessments.
For scientific information produced by Bureaus of the U.S. DOI, refer to individual Bureau peer review websites.
NOTE: The Bureau of Indian Affairs (BIA), Office of Historical Trust Accounting (OHTA), Office of the Inspector General (OIG), Office of the Secretary (OS), Office of the Solicitor (SOL), National Business Center (NBC), and Office of Special Trustee (OST) do not believe they currently produce or sponsor the distribution of influential scientific information (including highly influential scientific assessments) within the definitions promulgated by the Office of Management and Budget. As a result, they have no agenda of forthcoming influential scientific disseminations to post on their websites in accordance with OMB's Information Quality Bulletin for Peer Review.
