1955年5月至7月，在Tuktoyaktuk附近对Ibyuk和Sitiyok冰丘进行了调查。前者位于前湖中心，高42米，底部周长900米;后者高10米，周长210米。描述了内部冰体和覆盖沉积物，并估计冰丘年龄为7- 10，000年的Ibyuk，4000年的Sitiyok。发生晚威斯康星州冰川表示在伊比尤克地区和某些均衡运动的麦肯齐三角洲。大地升起了。在过去的12，000年中，约40米，冰川作用也引发了约30米的淹没和随后的出现。
Reports investigations of the Ibyuk and Sitiyok pingos near Tuktoyaktuk, in May-July 1955. The former in the center of a former lake is 42 m high, 900 m in circumference at base; the latter 10 m in height, 210 m in circumference. The internal ice bodies and covering sediments are described and pingo age is estimated as 7-10,000 yrs for Ibyuk, 4000 yrs for Sitiyok. Occurrence of a late Wisconsin glaciation is indicated in the Ibyuk area and certain isostatic movements in the Mackenzie Delta. The land rose approx. 40 m over the last 12,000 yrs, also submergence of about 30 m with subsequent emergence was initiated by glaciation.
