Spore‐ and pollen diagrams from samples at five different depths in theyedomasediments of the Duvanyy Yar exposure on the Kolyma River were analyzed. For each sample range diagrams (diagrams of percentage occurrence of the species identified in the sample, in terms of the present vegetation) were compiled in order to locate the best match in terms of species composition in the present vegetation. This technique permits an evaluation of the probable climate at the time of deposition. The results indicate that the oldest deposits (at a depth of 47 m) correlate with the second period of the Zyryan Glaciation; samples at higher levels derive from the Kargin Interstadial and the subsequent Sartan glacial phase. The range diagram technique suggests that conditions during the Kargin Interstadial matched those of the Holocene quite closely.
