Description :
The age of recent glacial, glacifluvial/fluvial forms is determined using lichenomeric dating in 2 Alpine valleys of the Massif des Ecrins. A lichen growth-curve is based on data from natural sites, such as boulder-fields, moraine ridges etc. of known age on recently deglaciated terrain. Analysis of the systems of terraces and paleochannels of the proglacial rivers supported by lichenometric dating allows 3 periods of intensified fluvial activity to be distinguished for the Little Ice Age.
