Hey Dave, experience tells me, crotch figure will be just at and below the crotch and usally only 2 - 4 boards thick, starting at the pith. The way this one is swolen, I wouldn't be suprised if the figure is a little bigger in this log. Thanks for the side view... :-D Looks like you got a nice turning piece there. Should make for some interesting stock.
You might want to consider seeing if you can get it to splat after you saw it up. Wet it down with rain water, keep it sealed in a plastic trash bag, keep it at around 80 degrees for a few months and see if it's going to splat any.
Thanks
