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.

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.
Salazar, Strickland Encouraged by discussions with Governors Concerning Gray Wolves

Lakewood, CO -- At a meeting today with the Governors from Idaho, Montana and Wyoming, Secretary of the Interior Ken Salazar and Assistant Secretary for Fish and Wildlife and Parks Tom Strickland discussed a path forward regarding the Northern Rocky Mountain gray wolf population.
“The successful recovery of the gray wolf is a stunning example of how the Endangered Species Act can work to keep imperiled animals from sliding into extinction,” said Secretary Salazar. “Today's meeting was very constructive and I appreciate that the Governors' share our goal to delist the species with a responsible approach guided by science.”
“There are many complexities involved in how we conduct the delisting,” said Assistant Secretary Strickland. “In today's meeting we discussed how we move forward to both delist the wolf and provide appropriate protection in the future.”
In April of 2009, Secretary Salazar affirmed the decision by the U.S. Fish and Wildlife Service to remove gray wolves from the list of threatened and endangered species in the northern Rocky Mountain states of Idaho and Montana and parts of Washington, Oregon and Utah. Wolves will remain a protected species in Wyoming.
Recently a federal judge in both Wyoming and Montana ruled against the Department on the delisting and on related issues, and wolves currently remain listed under the Endangered Species Act in all three northern Rocky Mountain States.
