  abstract = {{A}n accurate review of the literature on surface exposure dating methods shows evidence of the difficulty in applying cosmogenic dating methods to old moraines because of the intensity of late {Q}uaternary erosion processes. {M}oreover, as in some previous cases, we also found special difficulties in applying these methods to {LIA} moraines, caused by the intensity of current paraglacial processes. {T}he objective of this study is to apply cosmogenic dating methods to very old and very young moraines, which in both cases have been or are being affected intensively by erosion. {W}ith this purpose, we collected samples of boulders from moraines corresponding to (i) the penultimate glaciation and (ii) the {L}ittle {I}ce {A}ge ({LIA}), both from {S}ierra {N}evada in the south of the {I}berian {P}eninsula. {T}he sampling strategy was based on a preliminary accurate analysis of the geomorphological settings of two valley sites that resulted in the collection of only four boulder samples from an old moraine and three more from a very recent moraine. {U}sing in situ-produced cosmogenic {B}e-10 to date these boulders, the old samples yielded an age of ca. 130-135 ka for moraine stabilization. {T}he younger samples indicate that the {LIA} moraine accretion probably occurred between the fourteenth and seventeenth centuries, with a subsequent stage of accumulation during the nineteenth century as suggested by historical documents. {D}ating a glaciation that occurred prior to the last {P}leistocene glacial cycle and dating {LIA} glacial stages are novel in the context of {I}berian glaciations and agree with other palaeoenvironmental studies in {I}berian and in other {E}uropean mountains. {T}he limited number of boulders adequate for cosmic -ray exposure dating prevents statistical methods to be applied, and therefore highlights the need to improve geomorphological criteria in sample selection.},
