“…Lacustrine turbidites are well known (e.g., Houbolt and Jonker, 1968;Lara and Sanders, 1970), including those in glacial or periglacial environments (e.g., Church and Gilbert, 1975;Gruszka, 2007;Sauerbrey et al, 2013). Examples of dunedamming of fluvial channels include those from the Pleistocene and Holocene Nebraska Sands Hills (Loope et al, 1995;Muhs et al, 2000) and the Holocene of the Lake Superior area (Loope et al, 2004).…”
