 "Where? Where are the dust layers in peat deposits, lake deposits, deep sea 
cores, ice cores from Greenland and Antarctica for example?
All there is, is a set of narrow tree rings. No more."

Actually, there are sulphur spikes in ice cores which correlate to the tree 
ring narrowing. This also correlates with an explosion of Kraka Toa
