Earlier phases of the LIA in the Italian Alps are recorded byhistoric documents of the Ruitor floods. When in an advancedposition, the Ruitor Glacier dammed a lake, which producedrepeated outburst floods, damaging La Thuile & Aosta valleys.Ruitor delta-moraine(Favre,, 1864)The ice-dammedlake of Ruitor (La Thuile)in 1862Ruitor glacial ouburst floods:1284 ?1371 ÷ 1470 ?1594, 1595, 1596,1597,15981630, 1640, 1646, 1679, 168017511864LIA maxextentRuitor LakeRuitorGl.
The Little Ice Age in the Italian AlpsA few moraines/advanceadvance phases have been dated tothe first decades of the XVII century ( Miage, Lys,VerraVerra),but the best documented part of the LIA is in the first halfof the XIX century.In the Western Alps many glaciers reached their maximumextent in 1818-18201820. After a retreat in the 1830s a secondlargest advance occurred in 1845-18601860.In the Central Alps the Forni glacier reached its maximumsize in 1859.Since the second half of the XIX century the Italian glacierswere retreating, with only minor re-advancephases around1890-9595, 1920-2525 and 1965–19851985, reaching more and moreretreated positions.
