In 1903 Professor Samuel Jackson Barnett of Stanford University stated that his extensive studies with USGS on the coast in the Skagway area determined that there is a magnetic pole here!
Reported in the Philadelphia Record:
“The party made a special investigation in the peculiar magnetic disturbances which have made navigation difficult in certain localities. Near Skagway the disturbances are very severe the deflection of the needle being so great that the compass is rendered almost useless in that vicinity. It was found that this strange state of affairs was due to the abundance of magnetic rock in the locality. This rock is present in immense quantities on Douglas Island and on the mainland and near Skagway. Professor Barnett says that there was almost a perfect magnetic pole at that point.”
Hmmm, a perfect vortex of inestimable value!
