Ice Layer over spiders

• by wassock moderator

  Hi can anyone advise if the top of the ice layer is vaguely smooth regardless of what's underneath (within limits) or does it follow the contours, specifically of the spiders? Put another way, if the ice is generally 1 m thick does a 1m deep spider have 2m of ice over it?

  Hi Wassock,

  I am not sure about 2m of ice, but I would think that the channels perhaps have a slightly thicker amount of ice in comparison to the ice either side of that channel.

  I am probably wrong, but just visualise it being like 'opening the kitchen freezer door effect' where the air seems to 'fall' out of it, so perhaps forming thicker where lower.

  Just want to know if there's a valley in the ice or if its a smooth surface. Puzzling over why some white spiders stay white even though they are in the middle of dark fans.

  The (an) other scenario is that by the end of the summer the spiders have filled with dust so the surface is effectively flat when the ice starts to form.
