  abstract = {{T}hrough a detailed geomorphological study, including thourough mapping of the geomorphic features as well as {B}e-10 {C}osmic-{R}ay {E}xposure ({CRE}) dating, the geomorphological evolution of the {M}ulhacen cirque since the maximum ice extent of the last glacial cycle until nowadays was determined. {T}his glacial cirque is shaped on the northern face of the {M}ulhacen peak (3479 m a.s.l. 37 degrees 03'12 ' {N}/3 degrees 18'41 ' {W}), {S}ierra {N}evada, southern {S}pain. {I}t includes several depositional and erosional glacial landforms that allowed reconstructing its environmental evolution since the last glacial cycle. {F}urthermore, the sequence of glacial oscillations from this site was compared to that of other cirques of the massif, evidencing that: (i) new glaciers formed in these cirques during the {Y}ounger {D}ryas ({YD}), and (ii) disappeared at 11.7 +/- 1.0 ka. {D}epending on the altitude, orientation and height of the cirque walls, the final deglaciation of the cirques generated a diversity of landscapes, including a wide range of glacial and periglacial landforms, such as polished surfaces, sequences of moraines, proto-rock glaciers or large rock glacier systems. {N}o glaciers existed in the {S}ierra {N}evada during the {M}iddle {H}olocene. {O}nly the cirques whose summits exceed 3300 m, are north-exposed and whose walls exceed 300 m high (i.e. {M}ulhacen and {V}eleta) hosted glaciers during {N}eoglacial phases, including the {L}ittle {I}ce {A}ge ({LIA}) (approx.1300-1850 {CE}). {D}uring these periods, climate oscillations favoured the formation of small glaciers in these cirques, which generated large moraine systems with either one polygenic ridge or a sequence of spaced frontal arcs. {T}he existence of glaciers impeded the formation of permafrost-related landforms, such as rock glaciers and protalus lobes until the end of the {LIA}, when they started to form. {T}hese results are compared with the deglacial evolution in 55 cirques from {I}berian mountains as well as from glacial cirques from other mid-latitude mountains and subpolar regions. {T}he chronology of their deglaciation as well as the landforms generated during glacial retreat followed similar patterns, with no significant differences at regional scale. {F}or each mountain range, the geomorphological diversity existing in each cirque depends on the local topographic characteristics although they formed during the same climatic phases.},
