Возраст морен ледника Большой Азау в верховьях долины реки Баксан по дендрохронологическим данным
Basing on treering analysis of more than 150 pines growing in the Azau clearing, the minimum age of the deposits created by the Greater Azau Glacier was identified. Historical evidence, cartographic data, remote sensing materials, as well as the results of lichenometric studies and radiocarbon dating of buried soils were used as additional sources of information. We determined limits of the area covered by the glacier tongue at the end of the 19th century. It was also shown that the highest and most pronounced lateral moraine, conventionally called the «17th century moraine», was formed earlier than the end of the 15th century. Judging from the size of the maximum lichens of Rhizocarpon geographicum (120-130 mm) on its surface, the age of the moraine, determined by the dendrochronological method was found to be underestimated. It may be several centuries older than the end of the 16th century. We reexamined a pine trunk buried in the sediments at the bottom of the valley which was discovered in the 1960s...
