Taravilla Lake, Central Iberian Range, Spain
Moreno, A., Valero-Garces, B.L., Gonzalez-Samperiz, P. and Rico, M. 2008. Flood response to rainfall variability during the last 2000 years inferred from the Taravilla Lake record (Central Iberian Range, Spain). Journal of Paleolimnology 40: 943-961.

Moreno et al. conducted a sedimentological, geochemical and palynological study of Spain's Taravilla Lake (4039'N, 159'W) that revealed the presence of "allochthonous terrigenous layers that intercalate within the lacustrine sediments over the last 2000 years," which were formed "as the result of extreme hydrological events that caused higher clastic input to the basin." This work indicated that during the MWP, which they identify as occurring between AD 800 and 1300, "there is almost no evidence of flood deposits in the lake," in contrast to what was evident before and after it.
