The Andreevskaya Petroglyph
The Andreevskaya petroglyph (Opuokhalakh-Khaya according to Savvin, Suruktakh Khaya) is located on the left bank of the Sinyaya River, 133 km from its mouth and 3.5 km below the Matta River.
The site features nine planes with 276 drawings (anthropomorphic and zoomorphic figures, faces, birds, etc.) made in different colors of ochre.
Although the rocks are gradually decomposing, the preservation of the drawings is still satisfactory.
A two-layer altar was uncovered under the 9th plane. First layer – forged nail, small-caliber ammunition; second layer – four flint knife-shaped sheets, an end scraper, a fragment of pottery from the Ymyyakhtakh culture.
The monument is dated 2nd-1st millennia BC – 1st millennium AD.
