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 Land Buy-Back Program for Tribal Nations (Buy-Back Program) is committed toensuring that Indian landowners will receive fair market value for their fractional lands.
With the massive scope of the properties involved (more than 93,500 tracts on approximately 150 reservations), the Buy-Back Program plans to use mass appraisal techniques in which values are assessed simultaneously for many properties within a particular geographic area. This efficient and cost-effective process for valuations will be used to appraise homogenous, non-complex, vacant lands that have comparable land sales available. At the same time, recognizing that data limitations, non-homogeneous property types, and unique characteristics of specific properties may limit the use of mass appraisals, the Buy-Back Program will also employ project appraisals and property-specific appraisals as appropriate.
This strategy has been reviewed by The Appraisal Foundation (TAF), a non-profit, non-partisan organization that has been authorized by Congress to issue national appraisal standards and appraiser qualifications, and has previously provided the Department with guidance regarding valuation methods and techniques.
In addition to its determination that the Department's Valuation Plan, developed by theOffice of Appraisal Services in the Office of the Special Trustee for American Indians,represents a methodologically sound approach to meeting the requirements of the Buy-Back Program, TAF also provided a set of recommendations to further strengthen the program. The Department responded to those recommendations, which have been adopted and incorporated into the Valuation Plan.
In 2015, The Appraisal Foundation reviewed the implementation of the Program's appraisal method, which concluded that appraisals are being conducted appropriately and effectively.
