Summary
[edit].jpg&action=edit§ion=1){kind=link}
| Description | Ahh, that cool Alaskan fresh air! Here we see USGS geologist, Richard Lease, collecting samples of granitic bedrock high above Blockade Glacier in the Neacola Mountains of Alaska. Blockade is just one of the many glaciers in Alaska...but how many glaciers currently exist in Alaska? We don't know exactly. The number may be as large as about 100,000. Currently, there are about 2,000 Alaskan valley glaciers. Of these, about a third have been given official names by the U.S. Board on Geographic Names (geonames.usgs.gov). Most of the unnamed glaciers are small cirque and mountain glaciers. |
