The unique geological framework of the “los Llanos de La Larri” (Ordesa-Monte Perdido National Park) facilitated the genesis of a relevant juxtaglacial sedimentary record during the last glacial phase in the central Pyrenees. In this study we conducted a geomorphological and outcrop survey, an electric tomography study and the definition of the main sedimentological units by means of the study of 3 cores up to 17 m long. The combined study of surface and underground data has allowed us to define a paleolacustrine sedimentary sequence more than 40 m thick and the geometry and nature of the units of the infilling sequence. Radiocarbon dating indicate that the minimum age of this deposit is 35 ky (BP) at 17 m depth, and the infilling of the basin ends at 11 ky BP.
