Ok, then, I guess if you get in there and take various measurements, those rocky "steps" might actually pass the minimal IRC requirements, i.e., twelve inches wide, three inches deep and no more than 18 inches vertical from each other. Says nothing about maintaining the same distance between steps or that they all have to be the same width or anything like that. It specifically says these steps or rungs do not have to comply with 311.5 and 311.6.
