Pluvial Lake Shore Deposits
Pluvial lakes are lakes that existed in enclosed basins in the interior of continents during times of enhanced rainfall, reduced evaporation, or a combination of both. These lakes in many cases left a valuable record of paleoclimates in the form of lake sediments, of erosional shore features, and of gravelly to sandy shore deposits. Pluvial lake shore features have been recognized in many parts of the world, but are particularly well known from North America. Here, they were first described, identified, and interpreted in classical studies by geological pioneers I.C Russel (1885), and G.K. Gilbert (1890) who worked on the shore deposits of Lake Bonneville (“the proto Great Salt Lake”), a pluvial lake that existed during the Wisconsinan/Weichselian Ice Age.
In the last few years, Lake Bonneville shore deposits have received renewed attention. Many of the internal structures of these deposits remained unknown because of slumping or other types of outcrop deterioration. Only where gravel...
