Katmai is representative of the northern portion of the Alaska Peninsula and contains the Aleutian Range and the Nushagak-Bristol Bay Lowlands. The Aleutian Range province is characterized by the Shelikof Strait seacoast, the Aleutian Range and the lake region centered around Naknek Lake. The seacoast is a rugged, diversified area of narrow-to-wide bays, long and narrow-to-wide beaches, and intricate coves. Rivers cascade down steep canyons, and waterfalls plunge onto ocean beaches.The Aleutian Range is the backbone of the peninsula. The higher peaks of this range within Katmai National Park were formed predominately by volcanic action and rise steeply from the coastline to altitudes greater than 7,000 feet. The slopes and upper valleys surrounding these peaks contain glaciers on both sides of the Aleutian divide. Along the eastern coast of the park, a few of these glaciers descend almost to sea level. The largest glaciers in the park are 3 to 4 miles wide and 10 to 12 miles long.
