Location Description

Excavated; The sediments on the ridge are primarily eolian silts, overlying glacial outwash. The samples were recovered from the top three to five centimeters of excavation within the A horizon. This sediment layer is a brown silt, interpreted as eolian based on the uniformity of grain size and lack of gravels, with a heavy organic component. The A horizon ranges from one to five centimeters thick, and conformably overlies a modern B horizon which is currently undergoing pedogenic processes. The tephra did not form a discreet, continuous bed at this site. Rather, it was found in pockets between one-half and three centimeters thick throughout the A horizon. Pockets varied in size from a few centimeters to ten or twelve centimeters in diameter. Samples were collected from larger, more distinct pockets. The three samples were recovered from three different excavation units, with the largest pockets located at the western end of the excavation near the top of the south-facing slope.
