@peakbagger, I remember seeing some previous pictures you posted a while back, I think they were in response to a question about top covering.
I have the advantage of good sun and wind where I stack for seasoning (well, as much annual sun as one can get in close proximity to Mt. Washington). A couple examples are in the pictures. The first picture was from about a year ago. The splits were processed late spring/early summer and left uncovered until late August/early September. They were then moved into the firewood shed in early November and 6 of the 8 cords were burned last season. The second picture is the setup I am using currently. 4 of the stacks were processed last fall and top covered over the winter. The 5th stack was processed a couple months ago. These will be top covered late summer/early fall and will be moved to the firewood shed before the snow flies. The stacks are a mix of ash, beech, silver maple, white birch, and long dead red oak (all other oak is in a separate pile waiting to be processed for a 3-year turnaround). The firewood shed itself is an open design so it gets plenty of air to continue the seasoning process.
Going back to the original question about beech, I'm finally getting to a point where I will be 2-3 years ahead, so hopefully everything will have a minimum of 2 years to season. The third picture is what I have been scrounging this year (so far) and that will all be processed and stacked before winter. With that being said, over the last 11 years of using this wood stove, I haven't always had the luxury of having 3-year seasoned firewood and I never had an issue with birch, ash, or beech that only seasoned for a year (or less).
