Well I struck out on this one LOL. Thanks for the lesson. EDIT: I looked further into it and you're right that most of the PT is SYP, but they do make PT from DF. It has to go through an incising process first though. I know I've seen PT with those marks in it so it's good to know that those pieces are DF.
That might be for landscape timbers? You'll never see growth rings that tight on any PT SYP. If you ever buy non PT lumber look at the the growth rings too. If really tight its virgin growth timber. Looser rings are second/third generation hybrids made to grow faster. Ill always check the end grain of a 2x if I'm demoing an older home to admire the tightness of the virgin timber. Years back the lumberyard used to sell WRC dimensional lumber. I once counted over 200 growth rings on a WRC 2x4. Took that long to grow 3.5". Yes the tree nerd is strong in me! On a side note and sorry for the highjack Biddleman, if any cedar lumber is used for ground contact it wont last. The only one good for ground contact is Eastern red cedar. (think mailbox/fence posts, old clothesline poles etc). Unfortunately you cant buy it in board form unless from a private mill. The cedar at most lumberyards/box stores is a variety of Southern cedar. Some old lumberyards might still carry WRC stock. I recall buying a WRC 8' 6x6 for $180 in 2006! Needed for porch restoration.
Just think of it as a 4’x8’ sheet of plywood laying on the ground stacked 4 feet high over all of it. 4x4x8=128 cubic feet
