对克拉斯纳亚·高尔卡遗址的新调查表明，外贝加尔地区的晚更新世-早全新世出现了陶器。几个新的AMS测年获得的早期陶瓷文化层2表明，年龄在13900-10500 cal BP之间。首次给出了克拉斯纳亚·高尔卡沉积物的孢粉学研究结果，重建了晚更新世-全新世的环境变迁。从克拉斯纳亚·高尔卡剖面获得的花粉数据显示晚更新世环境条件寒冷干燥。在13900-12700 cal BP附近，该区域气候变得更加温和和潮湿，这与Allerød interstadial相对应，从而证实了放射性碳年龄的结果。晚更新世最温暖的时段出现在13500 cal BP左右。在12700和11800 cal BP之间，冷却可能对应于新仙女木的寒冷和干燥事件。在克拉斯纳亚·高尔卡考古遗址的沉积物中有一些地层。全新世早期和中全新世初期形成的沉积物很可能是由于侵蚀作用而被清除的。全新世晚期（2700-1800 cal BP），气候变暖，湿度增加。全新世晚期，气候不稳定。从400 cal BP开始，该地区的植被获得了现代的外观。在乌斯季-卡伦加十二世、斯图登诺一世和乌斯季-门扎一世地区，一些关于古气候重建的出版材料被认为是在该地区一般特征的背景下。因此，孢粉学重建和放射性碳年代测定都将克拉斯纳亚·高尔卡最早的陶瓷置于晚更新世-早全新世的最后阶段，即13900-10500 cal BP之间。
New investigations of the Krasnaya Gorka site suggest the emergence of pottery in the Late Pleistocene-Early Holocene in the Transbaikal region. Several new AMS dates obtained for the early ceramic cultural layer 2 indicate an age between 13900-10500 cal BP. The results of palynological studies of the Krasnaya Gorka deposits are given in the paper for the first time, and the Late Pleistocene-Holocene environmental changes were reconstructed. Pollen data obtained from the Krasnaya Gorka profile showed cold and dry Late Pleistocene environmental conditions. The regional climate became milder and more humid around 13900–12700 cal BP, which corresponds to the Allerød interstadial thus corroborating the radiocarbon age results. The warmest interval of the Late Pleistocene occurred around 13500 cal BP. Between 12700 and 11800 cal BP, cooling probably corresponds to the cold and dry event of the Younger Dryas. There is some stratigraphical in deposits of the Krasnaya Gorka archeological site. The deposits forming in the early Holocene and beginning of the middle Holocene most likely were removed by erosion. Warming and increased humidity occurred in middle of the late Holocene (2700-1800 cal BP). During the late Holocene, the climate was unstable. Beginning 400 cal BP, the vegetation of the region acquired its modern appearance. Some published materials concerning reconstructions of paleoclimate in the region of Ust’-Karenga XII, Studenoe I, and Ust’-Menza I are considered in the context of general characteristics of the region. Therefore, both palynological reconstructions and radiocarbon dates place the earliest ceramics from Krasnaya Gorka within the final stage of the Late Pleistocene – Early Holocene between 13900-10500 cal BP.
