Slope deformations of different types and ages are very common landforms on the southern coastal slope of the Crimean Mountains in Ukraine. The nature and activity of slope processes is changing over time, and different processes may even occur at the same place. Therefore, many slope deformations have polygenetic characteristics. Identifying and dating the individual processes that create the resulting slope deformation are crucial for understanding the landscape development and for assessing the potential hazards to inhabited areas. In this study, we report a detailed multidisciplinary analysis of the coastal complex slope deformation situated in the Laspi resort at the SW tip of the Crimean Mts. A nearly 200-m-long outcrop in the frontal part of the deformation was studied in detail. The base of the outcrop (overhanging the beach) contains remnants of rock avalanche deposits in the form of large limestone blocks.
