Dear et all;-
  Half way up the East side of Hudson Bay, around the Belcher Islands, is this two-thirds round singularity. Now, it seems to me that this could only have occured due to meteoric impact or massive volcanic explosion.
  If it's ever been mentioned in eather context---I missed it.
  Inquiring minds want to know!
