Abstract

The 1908 Tunguska event is used to be associated with a forestfall named after its first scientific researcher -- Leonid Kulik.However association of the Kulikovskii forestfall with the events in the morning of June 30, 1908 is based only on Evenks accounts. Initially, Kulik assumed the impact site was about 60 km east of this forestfall (unknown to him at that time). Then he received additional information about the existence of this large forestfall, and moved the search point. Later, some other forestfalls were reported, albeit of a much smaller area. Dates some of them can't be pinpointed accurately, i.e. only "about June 30", and so on. However Evenks reported about several small forestfalls in the region which according to them occurred on the same morning as the Kulikovskii one. But as they were much smaller then a little attention was paid to them (with the exception of the so-called Chuvar forestfall). This paper is devoted to consideration of these forestfalls (including some peculiarities of the Kulikovskii one). The paper focuses on facts (and not on interpretations), which any interpretation of the 1908 Tunguska event should explain.
