Thank you for that Eshmun. I am not a geologist but do have some questions. In your analysis you use geometry to compare the volume of the "saucer" with the company's estimate of the volume of gravel. Is it valid to assume that the topography of the site has remained constant. Also with erosion much of the lighter material which was part of the pipe will presumably have flowed "down the river". Would it be valid to apply a factor representing the volume of gravel in kimberlite to this calculation (I do not know what that factor might be, but perhaps you do). Lastly is there any information on the geological age of the topography, presumably it is very ancient.
