Carl,most likely it was Ironwood,different parts of the same tree can be quite different in appearence as to color,grain.Craig,yes,it is quite common in AZ,but south of me.It is now illegal to harvest ironwood in this state,unless it is on private property or was a flood washout,even then,you better be able to prove mother nature destroyed it.The limbs tend to be a lot darker than the inner trunk,less figure also.The most colorful,and the best grain would be the root ball,mostly underground,it has the flame orange figure etc.There is a tremendous amount of wastage when you cut up ironwood,as much as 75%to get the good pieces.Because of the current laws in this state and Mexico,Ironwood has become one of the rarer woods of the world,believe it or not.You have better sucess cutting it with a metel cutting band saw and blade,big hunks will eat a regular chainsaw blade in seconds,carbide is the way to go,of coarse the same applies to mesquite and catclaw Acacia,the chainsaw part,I mean.Craig,you ever get thru this way in the future,drop on by,I can see Jerome from our yard.
