10,000+ cubic yards? Good golly!! That’s a LOT of spoil."

Thanks for the "sanity check"!
The berm IS big -- it looms on the skyline when viewed from any part of the island:
~~~~~~~~~~~~~~~~
Goal: Estimate volume of spoil dirt in berm -- as disposed (pre-erosion)
~~~~~~~~~~~~~~~~
Width = ~10.5 yds Ground width -- (Average of several measurements as a GE point-to-point "Line")
Height = ~10.5 yds (SWAG: could be less)
Area = [Triangle] 1/2 W*H = 55+ Sq Yds
Length = ~175 yds (Length of the "peak ridge" measured in yds as a GE "path")
Volume = Area X Length = 55 sq yds X 175 yds = 9,625 cubic yds
Volume = (Rounded up to adjust for erosion: ~10K Cu Yds)
DISCLAIMER: This explanation took at least 20X the time I spent on the original estimate! '-)
EXERCISE: Give it a try for yourself! Use the 2-6-2017 overflight (the sharpest), and the GE measurement tools (in yards) as indicated. Notice how minor variations in measurement mount up -- when CUBED!
Please share with me your result(s). I'll consider them when revising! (It probably would be downward -- but by no more than 25%...)
Have fun!!!

P.S. At first, I thought I'd made a 5X error -- and was going to have to plead the "A.J.Foyt excuse"... '-}
