  abstract = {{I}n the context of global ice retreat, studying glaciers and glacier responses to present and past climatic variations provies information to understand their long-term evolution. {A}lpine and {P}yrenean glaciers have been the subject of paleoclimate studies but it is not the case of the {V}osges {G}r{\'e}seuses ({VG}), a low to medium elevation mountain range in northeastern {F}rance. {T}his project focuses on the analysis of the palaeoglaciers of this area, where many landforms suggest the presence of ice during colder periods. {W}e determined the locations of the paleoglaciers and mapped them by using the software {A}rc{GIS} and the tool "{G}la{R}e" ({G}lacier {R}econstruction). {W}e show that glaciers in the {VG} were not extensive and did not exceed 45 m thick. {W}e also dated moraines closest to the cirques using the cosmogenic 10 {B}e and confirmed that glaciers were indeed present in this area between 19.5 and 13.0 ka. {C}limatic reconstructions, obtained from {E}quilibrium {L}ine {A}ltitude ({ELA}), show that mean summer temperatures were between 1.8 and 2.4 degrees {C}, when considering precipitations equivalent to the current level. {G}laciers retreated before the {Y}ounger {D}ryas ({YD}) due to their small size, which differentiates them from the {V}osges {C}ristallines, where deglaciation occurred later. {F}inally, initial dating of the {R}ocher de {M}utzig, one the highest point of the {VG}, shows that an ice cap probably covered the massif until 38.000 years ago. {I}n a context of cold climatic episodes, it is interesting to link the glacial evolution and prehistoric population dynamics, that must have adapted to paleoclimatic conditions, closing of strategic paths and decreasing availability of ressources.},
