Interesting subject - would never have thought of making a round stack as described.
I very much doubt that would work very well where I live due to bears - both black and grizzly.
I made a lean-to wood shed and had it neatly stacked with wood for my workshop. One morning I went out and found the wood all scattered around. Each spring/summer, we have bears walk through the property looking for food - lots of berry bushes at the back area. Seem to be regular bears returning each year. This year for some unknown reason, the wood shed was pretty much emptied (wood scattered around) and several other piles turned over by the bears in their quest for food (rodents, grubs etc.). I also heard from the local post office, that one of the local s hot a black bear walking through property - wonder if it was our regular visitor ?
