Portage Indian Reservation/Isle Royale National Park:
The Anishinaabe Grand Portage Reservation is located in Cook County in the extreme northeast corner
of Minnesota, approximately 150 miles from Duluth. The camera looks to the east out towards
Isle Royale National Park, which is located in Lake Superior. Isle Royale National Park,
which was established in 1940, is a federal Class I area and, as such, receives special protection
from air pollution. The park encompasses a total area of more than 850 square miles and extends 4.5 miles outward from the
island (which is 45 miles long and 9 miles wide at its widest point) into Lake Superior. Roadless Isle Royale is accessible
only by boat or float plane. This area generally has lower levels of air pollution than urban areas in the Midwest.
The twin cities of Minneapolis-St.Paul located in Minnesota have
a combined population of about 3.5 million in the metropolitan
area. The camera looks to the west. Air pollution issues
in Minneapolis-St.Paul includes occasional high 8-hour ozone
levels during the summer (May through September) and high
24-hour fine particle levels throughout the year.
National Wildlife Refuge:
Seney, which was established in 1935 for the protection and
production of migratory birds and other wildlife, is located
in the Upper Peninsula of Michigan. The 21,150-acre wilderness
area in the refuge is a federal Class I area and, as such, receives
special protection from air pollution. The camera looks to the
north. The refuge generally has lower levels of air pollution
than urban areas in the Midwest.
