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:
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.
In February 2002, the Office of Management and Budget (OMB) issued a directive that all federal agencies issue and implement Information Quality Guidelines. In response to this directive, the Department of the Interior (DOI) issued and implemented guidelines to ensure and maximize the quality, objectivity, utility, and integrity of information disseminated by its bureaus and offices.
In order to ensure the accuracy and integrity of its published scientific information, DOI follows a robust peer review process wherein the information undergoes internal peer review and is subject to public scrutiny. DOI, its bureaus and offices, and the National Invasive Species Council maintain the highest standards possible for published information to ensure integrity and transparency.
DOI Bulletin for Peer Review
The OMB directive, Final Information Quality Bulletin for Peer Review (December 15, 2004), 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. DOI bureaus and offices created Web sites to accommodate the requirements of the Peer Review Bulletin.
