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 Secretary of the Interior's trust principles were first issued by Secretary Babbitt in April 2000 with Secretarial Order 3215. They were eventually incorporated into the Departmental Manual.
Trust Principles. It is the policy of the Department of the Interior to discharge, without limitation, the Secretary's Indian trust responsibility with a high degree of skill, care, and loyalty. The proper discharge of the Secretary's trust responsibilities requires that persons who manage Indian trust assets:
Protect and preserve Indian trust assets from loss, damage, unlawful alienation, waste, and depletion;
Assure that any management of Indian trust assets that the Secretary has an obligation to undertake promotes the interest of the beneficial owner and supports, to the extent it is consistent with the Secretary's trust responsibility, the beneficial owner's intended use of the assets;
Enforce the terms of all leases or other agreements that provide for the use of trust assets, and take appropriate steps to remedy trespass on trust or restricted lands;
Promote tribal control and self-determination over tribal trust lands and resources;
Select and oversee persons who manage Indian trust assets;
Confirm that tribes that manage Indian trust assets pursuant to contracts and compacts authorized by the Indian Self-Determination and Education Assistance Act, 25 U.S.C. 450, etseq., protect and prudently manage Indian trust assets;
Provide oversight and review of the performance of the Secretary's trust responsibility, including Indian trust asset and investment management programs, operational systems, and information systems;
Account for and timely identify, collect, deposit, invest, and distribute income due or held on behalf of beneficial owners;
Maintain a verifiable system of records that is capable, at a minimum, of identifying: (1) the location, the beneficial owners, any legal encumbrances (i.e., leases, permits, etc.), the user of the resource, the rents and monies paid, if any, and the value of trust or restricted lands and resources; (2) dates of collections, deposits, transfers, disbursements, third party obligations (i.e., court ordered child support, judgments, etc.), amount of earnings, investment instruments and closing of all trust fund accounts; (3) documents pertaining to actions taken to prevent or compensate for any diminishment of the Indian trust assets; and (4) documents that evidence the Department's actions regarding the management and disposition of Indian trust assets;
Establish and maintain a system of records that permits beneficial owners to obtain information regarding their Indian trust assets in a timely manner and protect the privacy of such information in accordance with applicable statutes;
Invest tribal and individual Indian trust funds to make the trust account reasonably productive for the beneficial owner consistent with market conditions existing at the time the investment is made;
Communicate with beneficial owners regarding the management and administration of Indian trust assets; and
Protect treaty-based fishing, hunting, gathering, and similar rights of access and resource use on traditional tribal lands.
