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.
A summary of DOI-specific and bureau-specific restrictions are listed below. If you are not certain if you are covered by one or more of the restrictions below, check with an ethics counselor from your office or bureau.
This regulation prohibits, with limited exceptions, all DOI employees, their spouses, and their minor children from acquiring or retaining any claim, permit, leases, small tract entries, or other rights that are granted by the Department in Federal lands. This prohibition does not restrict the recreational or other personal or noncommercial use of Federal lands by an employee, or the employee's spouse or minor children, on the same terms available to the general public.
This regulation applies to certain employees within the Office of the Secretary (OS) and other Departmental offices that report directly to a Secretarial officer who is in a position classified at GS-15 and above. Contact an ethics counselor from your office or bureau or refer to 5 C.F.R. § 3501.103(b)(ii) to see a list of affected offices. Employees in these offices may not acquire or hold any direct or indirect financial interest in Federal lands or resources administered or controlled by the Department. This generally includes stock or bond interests in most oil, gas, and mining companies that hold leases on Federal lands to conduct their operations.
Bureau of Land Management (BLM) employees are prohibited from voluntarily acquiring direct (owned by the BLM employee) or indirect (owned by the spouse or minor child of a BLM employee) financial interests in Federal lands. Prohibited interests include stocks, bonds, and sector mutual funds in oil, gas, geothermal, and mining companies that hold leases or other property rights on Federal lands. Prohibited interests also include companies that hold substantial Rights-of-Way on Federal lands. A BLM employee may not be a member or employee of a business that has interests in Federal lands, nor serve as a private sector real estate agent. Additionally, BLM employees may not occupy or use Federal lands (other than on the same terms as use of Federal lands is available to the general public), or take any benefits from Federal lands, based upon a contract, grant, lease, permit, easement, rental, agreement, mineral rights, grazing rights, or other holdings the BLM issues or regulates.
USGS employees are prohibited from holding financial interests in the mineral wealth of the United States and from executing any surveys or examinations for private parties. Prohibited interests include stocks and bonds in oil, gas, and other mining companies that hold significant leases on Federal lands. Annually, the USGS publishes a list of prohibited financial holdings in a Financial Guide for USGS Employees. Additionally, the USGS Conflict of Interest Policy sets limits on investments in energy sector mutual funds and entities engaged in mining activities on private land in the United States. The ability of USGS employees to own oil, gas or other mineral leases or receive royalties from those leases is extremely limited.

If you don't work for the OSMRE but have responsibilities connected with mining and reclamation operations, contact an ethics counselor from your office or bureau to determine whether you are covered by this law.
Prohibited financial interests under this law include companies that are involved in developing, producing, preparing, or loading coal or reclaiming the areas upon which such activities occur.
30 U.S.C. § 1267(g) prohibits employees of state regulatory authorities who perform any function or duty under the Surface Mining Control and Reclamation Act of 1977 from owning any interest in coal mining operations. (See also30 C.F.R. Part 705.)
