From this teaser you may know that I recently spent time on Adak in the Aleutians , a chain of 69 islands, many of them volcanic, extending 1,200 miles from the mainland of Alaska towards the Kamchatka Peninsula in Russia.

Adak is: 2,700 miles from the north pole 2,700 miles from Davis, California where I live 1,300 miles from Anchorage, the biggest city in Alaska 870 miles from the Kamchatka Peninsula in Russia 450 miles from Dutch Harbor , the nearest inhabited place in the Aleutian Islands (if you’ve ever watched the reality TV series Deadliest Catch , you might have heard of it) At the same latitude as Vancouver, British Columbia Horticulturally speaking, in USDA hardiness zone 8, the same as Portland, Oregon and Seattle, Washington; Anchorage, in comparison, is in zone 4; Fairbanks, in south-central Alaska, in zone 2 Between the Bering Sea to the north and the North Pacific Oc
