Detailed field mapping, till fabric, granulometric, and thin section investigations indicate that a 500 m long unit of laminated tills and interstratified glaciofluvial and glaciolacustrine sediments, belonging to the Catfish Creek Formation and exposed along the north shore of Lake Erie, Ontario, were deposited contemporaneously into a proglacial lake by coherent subaqueous mass flows of till (subaquatic flow tills) accompanied by glaciofluvial and glaciolacustrine contribution from supra‐ and/or subglacial and ice marginal sources. Comparison with descriptions of other stratified tills suggest that several of them may have a similar origin.
