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.
Every day someone like you becomes a wildland wildfire fighter, a teacher, a trail-builder, a museum curator, or a park ranger. Discover your opportunities in national parks. Come to play. Come to learn. Come to serve. Develop your environmental leadership skills. Find a job. Be the next generation to preserve and protect these great places.
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.
DOINews: Montana/Dakotas and Bureau of Reclamation: Upper Missouri River Highlighted In America's Great Outdoors Rivers Initiative

FORT BENTON, Mont. – Department of the Interior Assistant Secretary for Water and Science Anne Castle and her deputy assistant John Tubbs saw firsthand on Thursday, July 26, what hard work and collaboration by multiple partners – federal, state, and local – can accomplish. The pair toured a small segment of the 149-mile Upper Missouri Wild and Scenic River to learn about ongoing projects that promote riparian restoration and cottonwood recovery along the river corridor. Representatives were on hand from the Bureau of Land Management; Bureau of Reclamation, U.S. Geological Survey, U.S. Fish and Wildlife Service, Montana State Department of Natural Resources and Conservation, Missouri River Conservation Districts, and Friends of the Monument.
The BLM officials – Montana/Dakotas Associate State Director Kate Kitchell and Central Montana District Manager Stan Benes – hosted the day's event that ended with a tour of the Missouri Breaks Interpretive Center located in Fort Benton.
“The Missouri Breaks Monument is living proof that conservation is indeed a part of the BLM's multiple-use mission,” Kitchell said. “It's a priority of Secretary Salazar to conserve and restore key rivers across the nation, expand outdoor recreational opportunities, and support jobs in local communities. The BLM, with the help of its partners, is doing just that."
The Bureau of Reclamation's Platte River Recovery Implementation Program in Nebraska and the San Juan River Habitat Restoration in New Mexico are also key parts of the Great Outdoors Rivers Initiative. Together, these projects will work to improve habitat for the recovery of endangered species, such as, whooping cranes, interior least terns, piping ploves, and pallid sturgeon, while also benefitting habitats on national parks, tribal and private lands enjoyed by outdoor recreationists.
For the past 10 years the Central Montana District of the BLM has worked diligently to improve riparian corridors along the Upper Missouri River. That effort has included changes in the grazing program, moving away from hot season grazing, and reducing numbers where trends were not in a positive direction. In July 2010, with the assistance of the National Riparian Service Team, a Proper Functioning Condition assessment was initiated to summarize riparian conditions along six reaches of the Upper Missouri River. All reaches were found to have riparian-wetland plant communities playing a key role in ecological function along the Upper Missouri River and, most importantly, to be functioning properly. Along with the riparian assessment was an interagency effort with the Bureau of Reclamation to assess the need for cottonwood restoration along the same reaches of the Upper Missouri River. A 12-year working partnership with USGS has provided solid science to assist in several cottonwood seedling planting proposals, along with a draft Memorandum of Understanding suggesting the benefit of releasing waters from several dams during high water event years to provide productive seedbeds for future cottonwood stands. Both efforts are ongoing.
