Visit Arches and discover a landscape of contrasting colors, landforms and textures unlike any other in the world. The park has over 2,000 natural stone arches, in addition to hundreds of soaring pinnacles, massive fins and giant balanced rocks. This red rock wonderland will amaze you with its formations, refresh you with its trails, and inspire you with its sunsets.
A rugged, whitewater river flowing northward through deep canyons, the New River is among the oldest rivers on the continent. New River Gorge National River in West Virginia encompasses over 70,000 acres of land along the New River, is rich in cultural and natural history, and offers an abundance of scenic and recreational opportunities.
Denali is six million acres of wild land, bisected by one ribbon of road. Travelers along it see the relatively low-elevation taiga forest give way to high alpine tundra and snowy mountains, culminating in North America's tallest peak, 20,310' Denali. Wild animals large and small roam un-fenced lands, living as they have for ages. Solitude, tranquility and wilderness await.
USGS -- Developing a better method for diagnosing avian botulism
Avian botulism is a paralytic disease caused by one of the deadliest toxins known to mankind. It is produced by a naturally occurring bacterium, Clostridium botulinum, and when environmental conditions cause the toxin to accumulate in their food supply, botulism can kill thousands of birds each year. Under a Cooperative Research and Development Agreement, the USGS, through its National Wildlife Health Center Diagnostic Microbiology Laboratory, with support from the Great Lakes Restoration Initiative, is developing a rapid method for detecting a Type E avian botulism that causes mortality in fish-eating birds. This method uses a fluorescence-based bioassay and would potentially eliminate the need to use laboratory animals in mouse lethality assays. The new assay method will also be less labor intensive and faster so it will facilitate analysis of the large number of samples required to conduct meaningful ecological studies. This method may also have applications for human health since Type E botulism can occur in humans following consumption of improperly prepared fish.
