Evidence of the Little Ice Age in Southeastern Peru
Goodman, A.Y., Rodbell, D.T., Seltzer, G.O. and Mark, B.G. 2001. Subdivision of glacial deposits in southeastern Peru based on pedogenic development and radiometric ages. Quaternary Research 56: 31-50.

What was done
Soil properties were analyzed from several glacial moraines located in the Cordillera Vilcanota and Quelccaya Ice Cap region (1330' to 1400'S and 7040' to 7125'W) of southeastern Peru to determine late Quaternary climate oscillations in this region via data pertaining to fluctuations of alpine glaciers.

What was learned
Following the Holocene Climatic Optimum, approximately 5000 years ago, several episodes of glaciation were noted throughout the region of study. However, according to the authors, "the most extensive [glacial] advance during the late Holocene in southern Peru occurred during the Little Ice Age and is dated to <394 100 cal yr B.P. in the Cordillera Vilcanota and <300 80 cal yr B.P. in the Quelccaya Ice Cap."

What it means
While climate alarmists continue to downplay, and even deny, a Little Ice Age influence on global climate, evidence to the contrary continues to mount.
