Text Description: 0.5 to 1 cm thick. Occurs as discontinuous pods in bedded clayey silt and clay near base of organic-rich silt (loess) with prominent log layers. The organic-rich silts underlie Holocene peat and thaw lake deposits. Tephra is at 23 m on figure 13 of Hamilton and Brigham-Grette (1991). Brigham-Grette, written comm. 31/10/2008.
