A recent study showed that protalus ramparts were self‐limiting in that beyond a certain size there was a transformation from stationary firn into a small glacier which would modify or destroy the original landform. Based on this model of protalus development a number of dimensional constraints were suggested. Measurements obtained from a number of protalus ramparts in an area of high debris production of the Canadian Rockies appear to support the model. © 1997 John Wiley & Sons, Ltd.
