Glacially transported boulders in the White Mountains (Lefka Ori) of Crete of

The first glacial evidence in the mountains of Crete was reported in the 80s and specifically on Mt Idi (Psiloritis, 2456m a.s.l.). Until recently, the claimed presence of a cirque with moraines at an altitude of just ca. 1945 m a.s.l. has been disregarded as too low to be glacial in origin. However, new evidence from the mountains of central Greece suggest that glaciers developed even in mountains which do not exceed 1800m in altitude. As regards the White Mountains (Lefka Ori) Nemec and Postma (1993) in their study ‘Quaternary alluvial fans in SW Crete’ claim that there are “much compelling geomorphic indication of probable cirque glaciers or an ice cap with glaciers” without providing any further details. They studied the alluvial fans in the south piedmont of the massif and argued that they were formed by large fluvial discharges associated with ice cap wastage in the White Mountains. The fans were dated to Middle Pleistocene with Uranium series. It is noted though that several later geomorphological studies do not report glacial deposits or landforms in the White Mountains. 

Traces of glaciation (?) in the White Mountains of Crete

In this project we plan to resolve this controversial issue with detailed field work and geomorphological mapping of possible glacial evidence. The characteristics of such sediments (erosion state, altitude, catchment area etc) could be then used to infer their relative age and place them on the paleoclimatic map with potentially huge implications on our understanding of climatic mechanisms such as air circulation patterns in the Mediterranean. If feasible, absolute dating of possible findings will be attempted.  It is within our ambitions to link the presence of glaciers and the abrasive sediment-laden glacial meltwater with the extensive karst network of this carbonate massif. Indicatively, in Lefka Ori there have been discovered and explored the two deepest karst caves (sinkholes) in Greece: the  Gourgouthakas cave and the Liontari cave , exceeding 1200m and 1100m in depth  respectively.
