Comments
EeRl-12, Lillooet: A dated cache pit was excavated in Fraser River overbank silt. The silt is capped by a paleosol that is overlain by 2.5 m of fluvial sand and gravel, the upper surface of which now constitutes a terrace 28 m above river level. In addition to dating the human occupation, the sample provides a minimum age for the underlying silt, a maximum age for fluvial aggradation that buried the cultural horizon, and an estimation of the minimum rate of downcutting for Fraser River during the past millennium.
