   With the exception of small pingos, most pingo ice cores have several ice types. The bulk of the core can be segregated ice, intrusive ice formed from the freezing of bulk water, or any combination of the two types. In addition, dilation-crack ice (tension-crack ice, Brown and Kupsch, 1974) is commonly the main ice type beneath the summit of pingos with craters.

   Pingo bearers walk to and fro with their burdens of fruit and vegetables, representing many varieties quite strange to us. The pingo is a long and flat piece of wood from the kittul palm, very tough and pliable. The coolie, having suspended his load to the two ends in baskets or nets, places the stave upon his shoulder at the middle, and is thus enabled by the elastic spring and easy balance of the pingo to carry great weights for a considerable distance. Some pingoes are made from the leaf-stalk of the coconut palm, which is even more pliable than the kittul.
