The Beinn Iutharn Mhor group
2 other listed summits sit in the same prominence group, with Beinn Iutharn Mhor as the independent hill at its head.
| Summit | Height | Drop |
|---|---|---|
| Mam nan Carn | 986 m | 76 m |
| Beinn Iutharn Bheag | 953 m | 105 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.
