Zuri-Makhi (according to the map Puri-Makhi) of Sergokala district, the author of this article discovered a celestine deposit. Due to the end of the field season it was impossible to trace the distribution of celestine-bearing strata in other points of the southwestern wing of the Mugrinsky anticline.

The study of the area of Mugrinskaya anticline allowed to find out that the celestine-bearing strata has a significant distribution over the area and is of interest as an object for staging prospecting and exploration works.

Many works have been devoted to the geology of the Crimean Peninsula and the eruptive rocks developed here, most of which are based on personal observations of researchers. However, in a number of these works and in subsequent summaries of the Crimea to date, sometimes repeated incorrect conclusions of some researchers. Incorrect conclusions can be found both in specialized literature and in various reference books and guides for tourists and excursionists. Misconceptions include, in particular, the question of the formation of the chaos of Alupka Park, which is the subject of this article. In the light of these perceptions, the chaos is explained as the result of a grandiose collapse of eruptive rocks, moved a considerable distance down the slope from the place of its original occurrence.
