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.
Interior, Energy, EPA Commit to Cooperative Working Group to Achieve Shared Goals on Navajo Generating Station in Arizona
WASHINGTON - Today the Department of the Interior, Department of Energy and the Environmental Protection Agency released a joint statement that lays out the agencies' shared goals for Navajo Generating Station (NGS) and energy production in the region served by NGS.
In the statement, the three agencies agree they will work together to support Arizona and tribal stakeholders in finding ways to produce “clean, affordable and reliable power, affordable and sustainable water supplies, and sustainable economic development, while minimizing negative impacts on those who currently obtain significant benefits from NGS, including tribal nations.”
In addition to identifying shared goals, the statement announces specific activities the agencies intend to take jointly to help achieve those goals. These actions include: 1) creating a long-term DOI-EPA-DOE NGS working group to; 2) working with stakeholders to develop a NGS roadmap; 3) committing to complete the second phase of the National Renewable Energy Laboratory's report on clean, affordable, and sustainable energy options for NGS; and 4) supporting near-term investments that align with long-term clean energy goals.
NGS is a coal-fired power plant located on the Navajo Indian reservation approximately 15 miles from the Grand Canyon and owned partially by the Interior's Bureau of Reclamation (Reclamation). Power from the facility is distributed to customers in Arizona, California, and Nevada. Reclamation's share of the power is used to move water to tribal, agricultural, and municipal water users in central Arizona.
The Department of the Interior, the Department of Energy, and the Environmental Protection Agency oversee other federal responsibilities or interests that relate to NGS. These include tribal trust responsibilities, protection of national parks and wilderness areas, visibility and public health protection, and clean energy development.
