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.
After you leave Federal service, 18 U.S.C. § 207 imposes certain post-Government employment restrictions that may limit the type of work you may perform for your new employer for certain periods of time. (See 5 C.F.R. § 2641.) The Procurement Integrity Act (see 41 U.S.C. § 2104 and 48 C.F.R. §§ 3-104.1 through .09) imposes additional restrictions for certain employees who participated in costly procurement work. Former employees who are carrying out official duties as an employee or as an elected or appointed official of a tribal organization or intertribal consortium are not subject to 18 U.S.C. § 207 restrictions if they advise the Government in writing of any personal and substantial involvement they had as a Government employee in connection with the matter. (See 25 U.S.C. § 450i(j).)
Lifetime Restriction [18 U.S.C. § 207(a)(1)]
If you participated personally and substantially in any particular matter (grants, contracts, licenses, permits, applications, litigation, etc.), involving specific parties, you may never communicate with the intent to influence on behalf of any non-Federal entity, to any Federal department, agency, or court regarding that same particular matter.
Two-Year Restriction [18 U.S.C. § 207(a)(2)]
For matters under your official responsibility during your last year of Government service, you are restricted for two years after you leave Government service from representing any non-Federal entity to any Federal department, agency, or court regarding those matters.
One-Year Restriction on Aiding and Advising [18 U.S.C. § 207(b)]
For one year after Government service terminates, you may not aid or advise any non-Federal entity (other than the United States) concerning any ongoing trade or treaty negotiation in which you participated personally and substantially during your last year of Government service.
