Answer:
Not really - most of the glacier ice in Alaska is only a few tenths of a degree below the melting temperature, except for a surface layer a few meters thick that is cooled during winter. As a consequence, most glaciers in Alaska are not frozen to their beds. These glaciers are referred to as "temperate" glaciers. Glaciologists refer to a glacier as a "cold" glacier if it is more than a few degrees below the freezing temperature throughout most of its thickness.
