Likewise, on November 12, 2012, the author of the Naturalis Historia blog posted a lengthy article on Lake Suigetsu (https://thenaturalhistorian.com/creationism/) which included a reproduction of Figure 7 from the Davidson and Wolgemuth (2010) paper. Alternating patterns of distinct laminae are commonly identified within glacial lake deposits and are generally interpreted in the following way: during the summer months as meltwaters increase flow to the lakes, layers of more coarse sediment are formed, whereas the decreased meltwater in winter results in thinner, more clay-rich layers.
A varve is defined as “A sedimentary bed or sequence of laminae deposited in a body of still water within one year’s time . The net result, in theory, is an “annual” varve consisting of a summer and winter depositional couplet layer.
Furthermore, these experimental results have been confirmed by field observations. Helens subsequent to the well-known May 18, 1980, eruption resulted in the formation of a 762 cm (25 feet) thick deposit consisting of many thin, alternating fine-grained and coarse-grained laminae very similar to varves. Six years ago the Bio Logos Foundation published an article entitled Christian Geologists on Noah’s Flood: Biblical and Scientific Shortcomings of Flood Geology (Davidson and Wolgemuth 2010).
