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.
S. 2898, H.R. 816, Orchard Detention Basin Flood Control Act
July 9, 2008
Mr. Chairman and members of the Subcommittee, thank you for the opportunity to testify on S. 2898, the Orchard Detention Basin Flood Control Act. S. 2898, which is substantively the same as the House-passed bill, H.R. 816, would release approximately 65 acres of public land within the Sunrise Mountain Instant Study Area (ISA) [now referred to as a wilderness study area under Section 603 of the Federal Land Policy and Management Act (FLPMA)]. The Sunrise Mountain ISA is located on the east side of the Las Vegas Valley and within proximity to Las Vegas. The BLM supports S. 2898, but would like to work with the Committee on an amendment to the bill.
The Orchard Basin Detention Project would provide much-needed flood control for the eastern portion of the Las Vegas Valley. The project is intended to protect the fast-growing Las Vegas area from flooding due in part to stormwater drainage. The BLM understands the needs of this growing area and supports efforts to protect both the expansion of the city and the natural surroundings of the Las Vegas area.
The Sunrise Mountain ISA includes 10,240 acres of BLM-managed land. The ISA lacks wilderness characteristics; it is in a clearly unnatural condition and does not offer outstanding opportunities for solitude or primitive recreation. Sections of the ISA are affected by numerous off-highway-vehicle routes and illegal trash dumping, and there are remnants of a copper mining operation from the early 1900s. Furthermore, a portion of the ISA's western section is adjacent to expanding land development that increases the likelihood of further disturbances and unauthorized uses of the lands. Releasing the ISA from wilderness study status would provide the BLM with additional management tools for managing human activities, such as mechanically removing litter and fencing off areas to protect sensitive resource values. It would also allow the BLM to address other vital management issues associated with the long-standing human uses affecting this area.
The BLM recommends that S. 2898 be amended to release the entire ISA (10,240 acres) from interim management of its wilderness values so that the lands can be managed for other multiple uses and under existing conservation agreements for the area.
Thank you for the opportunity to testify on S. 2898. We look forward to working with the sponsors and the Committee on this piece of legislation.
