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.

The bound, sequentially numbered volumes of all the Reports, Documents and Journals of the U.S. Senate and House of Representatives, constitutes an incomparably rich collection of primary source material on all aspects of American history. During much of the 19th century, especially in the pre-Civil War era, the Serial Set included materials originating not only from the U.S. Congress but also key Executive Department publications that were published only or primarily in the U.S. Congressional Serial Set.
This unique collection begins with Volume 1 in the first session of the 15th Congress (1817) and continues to this day. The Readex U.S. Congressional Serial Set (1817-1980) will contain all publications from the 15th through the 96th Congresses, together with American State Papers (a retrospective collection of materials originating from 1789 through 1838 but published in the second quarter of the 19th century). The Serial Set sequential numbering system was devised in 1895, and applied retrospectively to all previously published volumes.
The U.S. Congressional Serial Set will for the first time make available digital images of all the publications in this collection, including maps and color plates.
Digitized from the original print volumes in partnerships with leading academic institutions and government organizations, the set features high-resolution full-color digital images, fully searchable OCR-generated ASCII text and full bibliographic metadata for every publication. It is cross-searchable with American State Papers, 1789-1838, which contains every legislative and executive document of the 1st through 14th Congresses.
