ABSTRACT

The Central Alaska Network contains three park units: Denali National Park (DENA), Wrangell-St. Elias National Park and Preserve (WRST), and Yukon-Charley Rivers National Preserve (YUCH). All are larger than 100 mi2 (259 km2). This analysis focuses mostly on DENA. Only two urban centers, Anchorage and Fairbanks, are located near the Central Alaska Network. Figure 20.1 shows the network boundary along with locations of each park and population centers with more than 10,000 people. Emissions from urban centers in Alaska are not expected to be particularly important to the parks in the Central Alaska Network, although wildres and international pollution from urban, industrial, and agricultural sources can affect air quality-related values, including visibility, in these parks.
