直到在横贯北极山脉中部的一片广阔的蓝色冰原中。Achernar显示，在上一个冰川周期中，东南极衍生的冰相对持续地沉积。沿Law冰川活动边缘最新暴露的物质(1区)具有丘陵地形，过渡到相对平坦的区域(2区)，随后是一系列类似于2米高的连续、平行/次平行的山脊和海槽(3-5区)。整个冰川都是冰芯覆盖的。过去的表面变化
Till in an extensive blue ice moraine in the central Transantarctic Mountains at Mt. Achernar shows relatively continuous deposition by East Antarctic derived ice throughout the last glacial cycle. The most recently exposed material along the active margin of the Law Glacier (Zone 1) has hummocky topography that transitions into to a relatively flat region (Zone 2), followed by a series of similar to 2 m high continuous, parallel/sub-parallel ridges and troughs (Zones 3-5). The entire moraine is ice-cored. Past surface changes of
