THE AGE OF THESE ARTIFACTS

At the beginning of March 2018, New Tribal Art received the final report from Dr. James Feathers at the Thermoluminescence Dating Lab at the University of Washington.  

As you can see below:

 

The sandstone with glyphs was approx. 7100 years old.

The pyroclastic material approximately 600 years old.

The Ceramic partially covered with a pyroclastic material 430 years old.

The Glass pieces approx. 5500 years old.

The hard ceramic or rock piece 1800 years old.

The accuracy of Dr. Feather's tests is incredible.  I have a long-held theory that the last time the volcano erupted was in the year 1580.  This was confirmed by Dr. Feathers.  

The reason that date is important is it signals Sir Francis Drake's departure from Nova Albion.  Drake filled the arroyos with a silver slurry, and heavy rains were not allowed to run downhill via the natural course.  The water backed up into small steam vents and made its way down to the superheated rocks.  Too much water on the racks generated steam, and that buildup of steam caused the eruption of 1580.
