Plume!

[hotreds]

No! Sorry- the give away is, as was mentioned, the bands. They won't have plume on them! It does actually look more like dust or water impurities. It would be interesting to take a magnifying glass to that ceegar to see the white stuff up close. But, I'm afraid I'd hafta agree with those that say it isn't plume. Also don't know if five years is long enough for plume to develop. It's a veeeeery sloooow process.
