    That's what I was thinking.

    Maybe pare away half the posts?

    Or I could restart it from scratch if that's better.

    Thread moved to Earth Science with flamebait posts + replies splintered into a discussion that has remained in the UFO section.

    Right-o chaps, carry on!

    I've been thinking about the lifetime of this floating island.
    It's covered in fully-grown trees. It must be many decades old. Could be even older.
    Definitely not transient.

    Another question came up: what does the underside look like? It would "grow" down, under the weight, even as it grows up. I wonder if, at some point, it might drag on the bottom and eventually come to a stop.

    Floating islands are fairly common in northern bogs and peatland lakes - with the addition of an occasional gentle current, their naturally convex shapes could easily be rounded into a circle in the manner of ice circles.

    This one is apparently natural and used for inspiration, though it appears on a site advertising the construction of them: http://blog.dhec.co.za/wp-content/uploads/2011/09/Natural-FI.png
