Alaska is famous for its stunning glaciers, but have you ever wondered exactly how many glaciers are in this icy wonderland? The answer isn’t as straightforward as you might think because it depends on how you define and count glaciers. Let’s break it down for you in simple terms.
How Many Glaciers Currently Exist in Alaska? The Big Numbers
Researchers estimate there are anywhere from 27,000 to over 100,000 glaciers in Alaska. Why the huge range? It depends on the size and type of glaciers being counted. Some studies focus only on larger glaciers, while others include smaller, unnamed ones.
Here’s a quick snapshot of glacier data in Alaska:
- 100,000 glaciers: A broad estimate that includes small, unnamed glaciers.
- 27,000 glaciers: A more conservative count based on mapped glaciers using satellite technology.
- 5% of Alaska’s land: Glaciers cover about 29,000 square miles of Alaska, an area larger than West Virginia!
What Makes Counting Glaciers So Hard?
Counting glaciers in Alaska isn’t simple. Glaciers are constantly changing due to climate and environmental factors. Some are growing smaller, while others are merging or disappearing entirely, making it tricky to track the exact number.
Glaciers in National Parks
Did you know that about 25% of Alaska’s glaciers are located in national parks? That’s around 23,000 square miles of glacier-covered terrain. For example:
Bering Glacier: The largest glacier in North America, stretching over 5,000 square kilometers.
Columbia Glacier: One of the fastest-retreating glaciers in the world.
If you visit places like Glacier Bay National Park or Denali National Park, you’re guaranteed to see some of these breathtaking ice formations.
List of Glaciers in Alaska

- Educational Value: The glacier’s accessibility and visible signs of retreat make it a valuable educational resource for understanding the impacts of climate change.
- Location: Situated near Wrangell-St. Elias National Park, the Malaspina Glacier is a piedmont glacier.
- Size: It is one of the largest glaciers in Alaska, spreading over an impressive 850 square miles.
- Geological Significance: As a piedmont glacier, it is formed by the spreading of ice at the foot of a mountain range, creating a unique landscape.
- Location: Located near Juneau, Alaska, the Taku Glacier is one of the few glaciers in Alaska that is advancing.
- Notable Feature: Its advance is a rare occurrence among glaciers worldwide, as most are retreating due to climate change.
- Significance: The Taku Glacier’s behavior is closely monitored by scientists to understand the factors contributing to its advance, which could provide insights into glacier dynamics and climate resilience.
Other Notable Glaciers
- Location: Located in Chugach National Forest, Portage Glacier is about 50 miles south of Anchorage, making it one of the most accessible glaciers in Alaska.
- Accessibility: The glacier can be accessed by a day cruise on Portage Lake, offering stunning views of the glacier and surrounding waterfalls. Alternatively, visitors can hike the Portage Pass Trail for panoramic views of the glacier, lake, and Prince William Sound.
- Activities: In winter, when the lake is frozen, visitors can hike across it to the glacier. The area also offers snowshoeing and cross-country skiing opportunities along the Trail of Blue Ice.
- Location: Situated approximately 29 miles outside of Valdez, Worthington Glacier is easily accessible from the Richardson Highway.
