Just finished my first season with an insert (Jotul Rockland) and have used a store-bought log rack to stack splits up to now. I'd now like to begin the process of collecting, splitting, and stacking a few years' worth. The problem is that my backyard is mostly on a slope and the only good location (subject to sun and wind) is on the slope. Here is a picture of where I'd like to build a pile. Most of the current pile you see there is on the store-bought rack and seems stable. I'm thinking of putting 3 or 4 4x4's (or 6x6's) in the ground near the tree to the left of the current pile. There is room near the fence for 2 stacks wide and there is rock underneath. I'd like to run 2 stacks about 5 feet high from these posts up the slope (with 2x4's underneath) about 16-20 feet to about where the right side of the current pile ends and then maybe have additional support posts on the upper-side as well (or, not and have gravity hold the pile down). Anyway, I'm interested in any comments, advice, additional ideas on this. Thanks.
