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.
Statement by Interior Secretary Sally Jewell on the Wildfire in Arizona
Office of the Secretary
WASHINGTON, D.C. – Secretary of the Interior Sally Jewell issued the following statement today on the wildfire in Arizona:
“I am deeply saddened by the tragic loss of 19 members of the Granite Mountain Interagency Hotshot crew yesterday near Yarnell, Arizona. I join all Interior Department employees in honoring their courage and sacrifice and standing with their families in their time of grief. The word “hero” can be overused, but in this case the word fails to do justice to these firefighters who stood in the path of a roaring inferno to protect their communities.
“In May, I visited the National Interagency Fire Center in Boise, Idaho with Secretary Tom Vilsack and saw the professionalism and dedication of the members of the firefighting community as they prepared for this severe fire season. Just this last weekend, I met with a Hotshot crew in Utah and witnessed first-hand their commitment to our nation and emphasis on firefighter safety. We can never be vigilant enough when it comes to safety, and we will continue to seek new ways of keeping our firefighters safe.
“Today, 58 Interior Department employees are on the ground fighting the Yarnell fire, and we stand ready to provide whatever further assistance the state of Arizona and local communities need to extinguish the blaze and protect lives and property.
“As we as a nation and as a department mourn this terrible loss, I am reminded of the passage, ‘Greater love has no one than this: to lay down one's life for one's friends.' On this sad day, may all of us honor these 19 firefighters for their ‘greater love.'”
