  abstract = {{T}he objective of this study was to assess whether it is possible to obtain a comprehensive record of the last deglaciation from the small {P}ena {N}egra glacial cirque in a marginal mountain range in the {I}berian {R}ange (northern {I}berian {P}eninsula). {T}ire cirque is located in {S}ierra {C}ebollera, at an elevation slightly over 2000 m a.s.l. in the divide, and has relatively low elevational difference between its uppermost and lowest parts. {T}he {P}ena {N}egra glacial cirque was selected because of the presence of several lateral moraines indicating the occurrence of a glacial longue of 1.8 km length and a small rock glacier, enabling identification of the main glacial stages that affected the paleo-evolulion of the glacier. {U}sing cosmogenic exposure dating techniques and geomorphological mapping it was possible to reconstruct the historical {P}ena {N}egra glacier and to distinguish: (i) the maximum ice extent ({MIE}) at approximately 18-20 ka, coinciding with the {G}lobal {L}ast {G}lacial {M}aximum ({GLGM}), although the occurrence of a previous stage was not ruled out; (ii) a stage of glacial re-advance at 16-17 ka, coinciding with the {O}ldest {D}ry as, followed by rapid ice melting; (iii) the development of a rock glacier in a minor structural cirque near the headwall at 14-15 ka, when paraglacial processes were probably dominant; and (iv) evidence of ice melting in the uppermost cirque at 13.5 ka. {S}tudy of the {P}ena {N}egra glacier revealed the history of a minor valley glacier affected by distinct stages, including the formation of a small rock glacier in the final phases of deglaciation. {N}o evidence of a {Y}ounger {D}iyas re-advance was found.},
