Perhaps if one lets their imagination loose on this 1st thunderegg, there is a lake/pond above rocks & part of the lake empties down a crevice in rocks. Thundereggs do produce interesting inside patterns. Sometimes they need Further cuttings to see what is hiding inside. Years ago when I was cutting rocks, I always cut additional slices to what Was hiding beyond. Not only thundereggs, but agates, jaspers, etc.
