Which hill this one belongs to
Chimney Rock Mountain is not counted as an independent hill in its own right. In prominence terms it belongs to Slieve Donard (850 m) — the nearest Marilyn you can reach from this summit without first dropping below its key col, 526 m.
Grouping is by prominence alone: a summit belongs to the nearest higher Marilyn it connects to without a deeper intervening col. Over a large massif that can gather hills no one would walk in a single day, and which few would describe as parts of the same mountain — it is a measure of independence, not a suggested route.
