Sikachi-Alyan 4

The Sikachi-Alyan 4 rock art site is located on the right bank of the Malyshevskaya channel of the Amur River, 0.9 km from its mouth. Distance from Sikachi-Alyan 3 is 1.0 km, from Sikachi-Alyan 5 – 1.5 km. Petroglyphs are observed on vertical rock surfaces and on basalt boulders in the floodplain, the length of the petroglyph distribution site is about 150 m. Due to the change in the hydrological regime of the Malyshevskaya channel after the construction of the dam, the impact of the ice drift on the boulders with petroglyphs stopped. However, at the same time, the flood “washing” of the channel stopped, which intensified the accumulation of fine-grained alluvium, so the boulders are gradually silting up and disappearing in the thickness of sedimentary deposits.

To date, five boulders and two surfaces with petroglyphs are known within the Sikachi-Alyan 4 locality. Four boulders, documented by A.P. Okladnikov are not currently observed, since they are completely buried in the alluvium. One boulder was taken out by A.P. Okladnikov to Novosibirsk. The “Stone 87” described by A. P. Okladnikov does not correspond to the published drawing.

Petroglyphs of Sikachi-Alyan 4 were first investigated by the expeditions of A. P. Okladnikov (1958, 1963, 1969). In the course of these studies, five boulders and two surfaces with petroglyphs were identified and described.

In 2017-2019, with joint efforts of the Center for Paleo-Art of the Institute of Archeology of the Russian Academy of Sciences, the Khabarovsk Regional Heritage Preservation Center, and the RSSDA Laboratory at the site of Sikachi-Alyan 4 carried out a continuous mapping of a rocky cliff with petroglyphs and documenting all available surfaces with drawings (two surfaces) with the determination of their coordinates.
