Significance of the Trough
Although the fir sample from the trough (MMH-77) did not date, the trough yields other important information. Extensive deposition has buried the canal and trough by as much as 30 cm of sediment. Was this significant erosion and deposition in the small rincon caused by the sheep and humans denuding the landscape around the homestead? Is that also why the large Douglas-fir beams were laid uphill from the corral (to prevent dirt from washing into the structure)?
