About 24K BTU's per cord, IIRC and 1000's of btu's is the right unit.
Amazingly little ash, easy to split, and plentiful, super plentiful. Throw a rock around here, hit a fir.
Big rounds are hard to split across, but not around the circumference, barring knots. When you have it narrower, it will split radially, more easily.
If it were me, I'd work around the edges by hand before going across them.
Some guys are just up to the challenge, and/ or have kids who would rather split wood than be cold.
soft Bigleaf maple is about the same BTUs, but ashy.
Madrona is premium here, along with hard to come by oregon white oak.

Flat, wide 'plates' of wood stack easily and fit on top of a bed of coals and wood more easily in my small wood stove. Wedges, from radial splitting, are sometimes harder to fit.
I kinda like the idea of splitting the edges off into a 'cant' shape that barely fits the stove on top of a bed of coals. Edges to build the bed of coals, then a big block of wood to burn through the night.
