Girdwood's Glaciers

Question: What are the names of the seven glaciers surrounding Girdwood, Alaska?

Answer: There are a large number of glaciers in the general vicinity of Girdwood, but the seven glaciers reference points to Crow Glacier, Raven Glacier, Eagle Glacier, Clear Glacier, Goat Glacier, Milk Glacier and Alyeska Glacier. Alyeska Resort's flightseeing page mentions other glaciers that are also within a relative short distance of Girdwood.

How many of "Feature X" exist in Alaska?

Question: How many rivers are there in Alaska? How many lakes? How about islands?

Answer: This is a type of question without a straight answer. It depends on how you define rivers and lakes, whether places that appear to be islands at high tide count and on the fact that parts of Alaska has not been mapped in high detail. Then there are physical processes that wipe out old features and create new ones.


With these cautions in mind, estimates of rivers, lakes and islands can be found at the Alaska Office of Economic Development's Alaska geography site at http://www.dced.state.ak.us/oed/student_info/learn/aboutgeography.htm. (Update October 2014: This website is no longer maintained by the Department of Commerce, Community & Economic Development's Division of Economic Development. You can find estimates of the numbers of rivers, lakes, and islands at the State of Alaska's Kids' Corner at http://alaska.gov/kids/learn/aboutgeography.htm.)

According to the United States Board of Geographic Names, there are 2,762 named islands, 3,388 named lakes, and 9,587 named streams in Alaska as of October 2014. You can download the entire dataset at http://geonames.usgs.gov/domestic/download_data.htm.

What are the names of Alaska's glaciers?

Question: Where can I find a list of the glaciers in Alaska?

Answer: We have compiled a list of named glaciers located in Alaska at http://library.alaska.gov/asp/alaska_glaciers.html. This list does not represent all glaciers in Alaska because not every glacier in Alaska is named. If you're looking for reading/viewing material on glaciers in Alaska, check out this list in WorldCat, the world's catalog of library catalogs.

Update September 2014: Since the list above was created, four new glaciers have been added to the USGS's Geographic Names Information System. They are:

Glacier Name Location Latitude Longitude Topo map
Klawasi Glacier Valdez-Cordova 620516N 1444301W Gulkana A-2
Ch'atanalch'elt Li'a Kenai Peninsula 611627N 1520558W Tyonek B-6
Ted Stevens Icefield Valdez-Cordova 612000N 1465000W Valdez B-8
Noisy Glacier Kodiak Island 581608N 1545148W Mount Katmai B-3
