Janet R. Collins On the Arctic Frontier: Ernest Leffingwell's Polar Explorations and Legacy


In May of 1906, Ernest Leffingwell and Ejnar Mikkelsen, co-commanders of the Anglo American Polar Expedition, sailed from Victoria, British Columbia to determine if there was land north of Alaska. The following spring they barely survived their trip on the pack ice off the northern coast of Alaska. However, between 1906 and 1914, Leffingwell defined and mapped the geography and geology of northeastern Alaska, including the coastline, and he studied the formation of permafrost.
