  abstract = {{I}n the {M}{\'e}rida {A}ndes, a detailed deglaciation history reconstruction is difficult to achieve due to scattered deglaciation chronologies available. {T}his paper contributes with 24 exposure ages of glacial landforms sampled in the {G}avidia valley. {E}xposure ages were obtained based on terrestrial cosmogenic nuclide 10{B}e dating. {R}esults indicate deglaciation mainly occurred between {I}n the {M}{\'e}rida {A}ndes, a detailed deglaciation history reconstruction is difficult to achieve due to scattered deglaciation chronologies available. {T}his paper contributes with 24 exposure ages of glacial landforms sampled in the {G}avidia valley. {E}xposure ages were obtained based on terrestrial cosmogenic nuclide 10{B}e dating. {R}esults indicate deglaciation mainly occurred between ~21 ka and 16.5 ka and the complete deglaciation occurred at ∼16.0 ka. {T}he glacier retreated in two different phases. {T}he oldest one occurred since the {LGM} until middle {O}t{D} or the local climate event {E}l {C}aballo {S}tadial. {T}he youngest phase occurred at ages younger than ~16.5 ka until complete deglaciation. {A} combination of topographic features and changes in the paleoclimate conditions at the end of the {E}l {C}aballo {S}tadial seems leaded the fastest former glacier extinction. {T}he topographic feature which seems contributed to the fastest glacier extinction was the low valley bottom slopes. {I}n addition, exposure ages of the {G}avidia valley were integrated with deglaciation chronologies from the central {M}{\'e}rida {A}ndes to compare deglaciation histories. {A}synchronous deglaciation histories were observed. {L}ocal paleotemperatures and paleoprecipitations contrasts, different valleys aspects, insolation and catchments steepness could explain different deglaciation histories ~21 ka and 16.5 ka and the complete deglaciation occurred at ~16.0 ka. {T}he glacier retreated in two different phases. {T}he oldest one occurred since the {LGM} until middle {O}t{D} or the local climate event {E}l {C}aballo {S}tadial. {T}he youngest phase occurred at ages younger than ~16.5 ka until complete deglaciation. {A} combination of topographic features and changes in the paleoclimate conditions at the end of the {E}l {C}aballo {S}tadial seems leaded the fastest former glacier extinction. {T}he topographic feature which seems contributed to the fastest glacier extinction was the low valley bottom slopes. {I}n addition, exposure ages of the {G}avidia valley were integrated with deglaciation chronologies from the central {M}{\'e}rida {A}ndes to compare deglaciation histories. {A}synchronous deglaciation histories were observed. {L}ocal paleotemperatures and paleoprecipitations contrasts, different valleys aspects, insolation and catchments steepness could explain different deglaciation histories.},
