Very pretty but examples of how not to season wood. Stacking to promote air circulation and a roof are essential.
I’m curious how the core would dry too. My suspicion is that that they would sit for a few years so the drying rate may just be slower. It must be a centuries old stacking style.
I stacked peat in a similar way, with no tarp or weather proofing in Orkney which has a notoriously poor climate. Peat once initially dried changes it’s structure and can withstand a certain amount of exposure to rain without reducing it’s burnability.
The wood I stacked last year in an open shed with a tin roof has shrunk from being tight against the roof to about six inches or so below it. The wood I transferred from a shed which had limited airflow and that had started to grow a fungus ( mostly on Beech logs ) immediately stopped once stored with more airflow.
