Thanks Pixie, that's some great information in there and confirms that my suspicions were certainly in the ballpark or even spot on.
Just enjoying a quite night right now with the husband and huskies after saying goodbye my mother in law knowing that she had a great visit
Back to Aerlaan tomorrow night.
Kacey, if you read this post you will find Pixie's post re: oceanic/oceanic plate subduction very helpful and informative.
