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.
Salazar Releases Long-Term Report Detailing Glaciers Shrinking in Alaska and Washington
WASHINGTON, D.C. – A report on long-term glacier measurements released today by Secretary of the Interior Ken Salazar shows that glaciers are dramatically changing in mass, length and thickness as a result of climate change. Over the past 50 years, U.S. Geological Survey (USGS) scientists have monitored the melting of Alaska's Gulkana and Wolverine Glaciers and Washington's South Cascade Glacier, yielding the longest such records in North America.
“This report we are releasing today is great example of the science and data our Department has gathered over the past 50 years,” said Secretary Salazar. “This information is helpful in tackling the effects of climate change and it is exactly the kind of science we need to invest in to measure and mitigate the dangerous impacts of climate change.”
Glacier shrinkage has global impacts, including sea level rise that threatens low-lying and coastal communities. Smaller glaciers will also result in a decrease of water runoff, and impacts are especially important during the dry late summer when other water sources are limited.
“There is no doubt that most mountain glaciers are shrinking worldwide in response to a warming climate. Measuring changes in glacier mass provides direct insight to the link between glaciers and climate, ultimately helping predict glacier response to anticipated climate conditions,” said USGS scientist Edward Josberger.
The three glaciers monitored in this study are known as benchmark glaciers. They are widely spaced, represent different climate regimes, and can be used to understand the thousands of other glaciers in nearby regions.
USGS scientists study glacier behavior during different seasons, including summer melt and winter snow accumulation, as well as their response to both short and long term climate variations. This allows for more detailed insight regarding how and when the climate is changing.
“In addition to these three glaciers, more than 99 percent of America's thousands of large glaciers have long documented records of an overall shrinkage as climate warms,” said USGS scientist Bruce Molnia. “Many people are surprised to learn that a few glaciers are thickening and advancing. These glaciers are responding to unusual and unique local conditions, including having large, high elevation areas where snow accumulates. Except for these anomalous few , most of America's glaciers are shrinking and these exceptions emphasize how natural variability is an inherent part of a complex Earth system.”
