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.
DOINews: New Publication on Karst Ecosystems and Climate Change
In the Karst Ecosystems and Climate Change project, which was partly funded by the South Central Climate Science Center, researchers are assessing the links between climate, groundwater storage, spring flow, and ecosystem response in two contrasting major U.S. karst systems: the Edwards and Madison aquifers. Three models have been customized or developed--a high-resolution climate model, a rainfall-response model, and a species sensitivity model--that are then linked to investigate how forecasted climate scenarios might affect species supported in these two karst areas. The first publication of this study (Long and Mahler, 2013) describes the development and application of a rainfall-response model that will be used to forecast future responses to climate change in these two aquifers. Model results also were used to classify aquifer-response characteristics related to climatic cycles.
