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 NRDA Restoration Program funds a portion of damage assessment cases undertaken. The funding for these cases comes from annual appropriations and from reimbursed costs recovered from responsible parties in other settled cases. In addition to the appropriated funding for damage assessment, the Program utilizes an average of $2.0 million annually in recovered funds to initiate new and supplement ongoing assessment needs. Co-Trustees (other federal agencies, states, Indian tribes or foreign governments), potentially responsible parties and the National Pollution Funds Center can also provide funding.
Once projects are funded, the NRDA Retoration Program makes use of project performance information to inform future funding decisions. Funding decisions are weighted towards cases that show progress along the damage assessment continuum towards settlement and eventual restoration. Cases that stall or fail to progress are considered a lesser priority, but are given direction to make course corrections at a stable or reduced funding level. The Program requires its case teams to document their respective assessment costs and attempt to recover those costs from the potentially responsible parties when negotiating settlements.
