But we don't know specifically if it holds true for the location of this object, or whether the object could have itself still been covered with halmeda, or covered with something else by 2012, or whether the object might have been pushed elsewhere by 2012.
..or salvaged by space aliens. What's your point?
My point is that this object should have been a key focus of the 2012 expedition, whether or not it was found again by Craig Cook, whose interests lie elsewhere. You (TIGHAR) were aware of it as of September 17, 2011, Jeff Glickman thought it was man-made and scaled properly by the fish, yet as far as I can tell, Phoenix whom you hired to search the area were not even aware of the existence of this potentially important object.
How you could have squandered so much on the "Bevington Object" (time, effort, PR and financial resources) and ignored this other promising find is, honestly, beyond my comprehension.
