Z genezy stożków kemowych

In North-East Poland, in the Riss Glaciation zone there occur hills of a characteristic conical shape. They have asymmetric slopes: one is usually short and steep, the opposite is longer and softer. They are connected with depressions left by blocks of dead ice and usually situated on the border of such basins. They are built of fluvioglacial deposits, sometimes with added ablation clays. They are formed through the accumulation of deposits into cones in large fissures of ice slopes. Their genesis is shown by their inner structure. All the layers originate in the culmination of the cone and thin out in accordance with the longer slope; the measurements of their dip direction indicate a fanshaped disposition of the directions of transport. By way of example two such forms have been described; they are situated in the western part of the Białystok Upland and in the North-East part of the Wysokie Mazowieckie Upland. Because of their morphometric and structural features they are called came cones (R. F. Flint 1957, A. Karczewski 1971, A. Musiał, K. Straszewska, M. Ziembińska-Tworzydło 1982, A. Musiał 1983).
