The excursion to the interfluve area between the rivers Lena and Amga attempted to show the participants of the Symposium the characteristics of alass-type landforms, the stages in the development of thermokarst, and the hills (bulgunniakhs) which result from prolonged frost heaving and are closely related to alass basins. In addition, a study was made of the lake basins on the Peystyakh terrace (though they are essentially non-thermokarstic) and the relationships were examined between these and several types of landforms. Discussions in the field largely omitted the main topics of the excursion and concentrated instead on little-known and unsolved problems of the development of the environment in Central Yakutia. Many questions were raised about the age, morphogenesis and structure of the landforms. These are discussed and elucidated in the present paper.
