Coastal Regions & Maps
This region is characterized by a chain of volcanic islands stretching across 1,800
km separating the Bering Sea from the Pacific Ocean. Fourteen large islands and
55 smaller islands define this archipelago most of which fall within the Alaska
Maritime National Refuge. These virtually treeless islands are either shrouded in
rain and fog or high force winds.
The Aleutian coastline has a repeating pattern of grassy hillsides, wave-pounded
cliffs with waterfalls, and acres of kelp beds. With an average tidal range of 3
feet diverse areas of marine life are found in semi-exposed shallow reefs.
