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.
HANOI, Vietnam – U.S. Secretary of the Interior Sally Jewell today concluded an official visit to Vietnam where she met with senior government officials, including Prime Minister Nguyen Tan Dung, to discuss ways the United States and the South Asian country can work together to combat the world’s growing trade in illegal wildlife, which threatens to push to extinction species ranging from elephants and rhinos to marine turtles, tigers and pangolins.
“Both Vietnam and the United States have a role to play in shutting down illegal trade in wildlife, and it is critical that we collaborate in our mutual efforts to crack down on poaching and trafficking by international criminal organizations,” said Jewell. “We had productive meetings and leaders of both nations recognize that we must take swift, effective action if we are going to shut down this trade that threatens to wipe out species around the globe.”
This year marks the 20th anniversary of normalized diplomatic relations between the United States and Vietnam. In addition to Prime Minister Dung, Jewell held meetings with Minister of Natural Resources and Environment Nguyen Minh Quang; Minister of Agriculture and Rural Development Cao Duc Phat; and Minister of Public Safety Tran Dai Quang.
Jewell also held a roundtable discussion with NGO leaders on wildlife trafficking and met with members of the Young Southeast Asian Leaders Initiative, U.S. President Barack Obama’s signature program to strengthen leadership development and networking in Southeast Asia. She also visited Cuc Phuong National Park to tour the Endangered Primate Research Center, Pangolin Conservation Program and Turtle Conservation Center.
Jewell will travel to China this week to hold meetings with Chinese officials on wildlife trafficking and also promote efforts to boost Chinese tourism to the United States in anticipation of next year’s Centennial of the National Park System.
