South West Alaska for the purposes of this website includes everything W of Unimak Pass out the Aleutian Islands to Attu. I used NOAA International Chart 513 of the North Pacific and Southern Bering Sea to locate the losses. The locations of each wreck, given in longitude and latitude, are of the geographic feature nearest the loss, not of the wrecks themselves. I will leave that to those who visit the actual areas and seek out evidence of the casualties. I am listing vessels alphabetically and setting a link as I complete each letter.
