Orowan(冰川学杂志，第一卷)10到30米的临界高度只适用于高度大于宽度的冰柱，而不适用于水平尺寸与高度相当的冰板。因此，只有冰山的高度或裂隙的深度将以这种方式受到限制；更宽广的裂隙，如通常在从不区域或紧密冰山或停滞冰川的墙壁中发现的裂隙，即使它们的温度处于冰点，高度也可能超过30米。
Orowan (Journal of Glaciology, Vol. I, NO.5, 1949, p. 235) the critical height of 10 to 30 m. applies only to ice columns with a height greater than their width, and not to ice slabs with horizontal dimensions comparable with their height. Therefore only the height of seracs or the depth of crevasses in a heavily dissected area would be limited in this way; more widely spaced crevasses, such as are generally found in the neve area or the walls of com-pact icebergs or stagnant glaciers, could exceed 30 m. in height even if their temperature were at freezing point.
