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.

Come to learn. Come to serve. Develop your environmental leadership skills. Find a job. Be the next generation to preserve and protect these great places.
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.
§102-39.5—How are the terms “I” and “you” used in this part?
Use of pronouns “I” and “you” throughout this part refer to executive agencies.
§102-39.10—What does this part cover?
This part covers the exchange/sale authority, and applies to all personal property owned by executive agencies worldwide. For the exchange/sale of aircraft parts and hazardous materials, you must meet the requirements in this part and in parts 102-33 and 101-42 of this title.
§102-39.15—Why should I use the exchange/sale authority?
You should use the exchange/sale authority to:
Reduce the cost of replacement personal property. If you have personal property that needs to be replaced, you can exchange or sell that property and apply the exchange allowance or sales proceeds to reduce the cost of similar replacement property. By contrast, if you choose not to replace the property using the exchange/sale authority, you may declare it excess and dispose of it through the normal disposal process. Any sales proceeds from the eventual sale of that property as surplus generally must be forwarded to the miscellaneous receipts account at the United States Treasury and thus would not be available to you.
Avoid costs (e.g., administrative and storage) that may be incurred when declaring the property to be replaced as excess and processing it through the normal disposal process.
The normal disposal process may include abandonment or destruction, reutilization by other Federal agencies, donation to eligible non-Federal public or non-profit organizations, or sale to the public. The time required to determine which of these options will apply and to complete the disposal transaction is likely to exceed the time required for an exchange/sale transaction.
§102-39.20—What definitions apply to this part?
The following definitions apply to this part:
Acquire means to procure or otherwise obtain personal property, including by lease.
Combat Material means arms, ammunition, and implements of war listed in the U.S. munitions list (22 CFR part 121).
Exchange means to replace personal property by trade or trade-in with the supplier of the replacement property.
Exchange/Sale means to exchange or sell non-excess, non-surplus personal property and apply the exchange allowance or proceeds of sale in whole or in part payment for the acquisition of similar property.
Executive Agency means any executive department or independent establishment in the executive branch of the Government, including any wholly owned Government corporation.
Federal agency means any executive agency or any establishment in the legislative or judicial branch of the Government (except the Senate, the House of Representatives, and the Architect of the Capitol and any activities under his/her direction).
Historic item means property having added value for display purposes because its historical significance is greater than its fair market value for continued use. Items that are commonly available and remain in use for their intended purpose, such as military aircraft still in use by active or reserve units, are not historic items.
Replacement means the process of acquiring property to be used in place of property that is still needed but:
No longer adequately performs the tasks for which it is used; or
Does not meet the agency's need as well as the property to be acquired.
Similar means where the acquired item and replaced item:
Are designed and constructed for the same purpose;
Constitute parts or containers for identical or similar end items; or
Fall within a single Federal Supply Classification (FSC) group of property that is eligible for handling under the exchange/sale authority.
§102-39.25—How do I request a deviation from this part?
See §§102-2.60 through 102-2.110 of this chapter to request a deviation from the requirements of this part.
Subpart B—Exchange/Sale Considerations
§102-39.30—When should I not use the exchange/sale authority?
You should not use the exchange/sale authority if the exchange allowance or estimated sales proceeds for the property will be unreasonably low. You must either abandon or destroy such property, or declare the property excess, in accordance with part 102-36 of this chapter. Further, you must not use the exchange/sale authority if the transaction(s) would violate any other applicable statute or regulation.
§102-39.35—How do I determine whether to do an exchange or a sale?
You must determine whether an exchange or sale will provide the greater return for the Government. When estimating the return under each method, consider all related administrative and overhead costs.
§102-39.40—When should I arrange for a reimbursable transfer of exchange/sale property to a Federal agency or other eligible organization, or sell such property to a State Agency for Surplus Property?
If you have property to replace which is eligible for exchange/sale, you should first, to the maximum extent practicable, solicit:
Federal agencies known to use or distribute such property. If a Federal agency is interested in acquiring and paying for the property, you should arrange for a reimbursable transfer. Reimbursable transfers may also be conducted with the Senate, the House of Representatives, the Architect of the Capitol and any activities under the Architect's direction, the District of Columbia, and mixed-ownership Government corporations. When conducting a reimbursable transfer, you must:
Do so under terms mutually agreeable to you and the recipient.
Not require reimbursement of an amount greater than the estimated fair market value of the transferred property.
Apply the transfer proceeds in whole or part payment for property acquired to replace the transferred property; and
State Agencies for Surplus Property (SASPs) known to have an interest in acquiring such property. If a SASP is interested in acquiring the property, you should consider selling it to the SASP by negotiated sale at fixed price under the conditions specified at §102-38.125 of this title. The sales proceeds must be applied in whole or part payment for property acquired to replace the transferred property.
§102-39.45—What prohibitions apply to the exchange/sale of personal property?
You must not use the exchange/sale authority for:
The following FSC groups of personal property:
11 Nuclear ordnance.
12 Fire control equipment.
14 Guided missiles.
15 Aircraft and airframe structural components (except FSC Class 1560 Airframe Structural Components).

Controlled substances, unless you meet the requirements of §101-42.1102-3 of this title.
Scrap materials, except in the case of scrap gold for fine gold.
Property that was originally acquired as excess or forfeited property or from another source other than new procurement, unless such property has been in official use by the acquiring agency for at least 1 year. You may exchange or sell forfeited property in official use for less than 1 year if the head of your agency determines that a continuing valid requirement exists, but the specific item in use no longer meets that requirement, and that exchange or sale meets all other requirements of this part.
Property that is dangerous to public health or safety without first rendering such property innocuous or providing for adequate safeguards as part of the exchange/sale.
Combat material without demilitarizing it or obtaining a demilitarization waiver or other necessary clearances from the Department of Defense Demilitarization Office.

You may use the exchange/sale authority only if you meet all of the following conditions:
The property exchanged or sold is similar to the property acquired;
The property exchanged or sold is not excess or surplus, and you have a continuing need for that type of property;
he number of items acquired must equal the number of items exchanged or sold unless:
The item(s) acquired perform all or substantially all of the tasks for which the item(s) exchanged or sold would otherwise be used; or
The item(s) acquired and the item(s) exchanged or sold meet the test for similarity specified in §102-39.20 that they are a part(s) or container(s) for identical or similar end items;
The property exchanged or sold was not acquired for the principal purpose of exchange or sale; and
You document at the time of exchange or sale (or at the time of acquiring the replacement property if it precedes the sale) that the exchange allowance or sale proceeds will be applied to the acquisition of replacement property.

The exceptions that apply to the conditions for exchange/sale §102-39.50 are:
You may exchange books and periodicals in your libraries for other books and periodicals, without monetary appraisal or detailed listing or reporting.
In acquiring items for historical preservation or display at Federal museums, you may exchange historic items in the museum property account without regard to the FSC group, provided the exchange transaction is documented and certified by the head of your agency to be in the best interests of the Government and all other provisions of this part are met. The documentation must contain a determination that the item exchanged and the item acquired are historic items.
Subpart C—Exchange/Sale Methods and Reports
§102-39.60—What are the exchange methods?
