Strata below it, where dated, were older still.

The sequence made geological sense.

The bones had been deposited in terminal Pleistocene sediments at a time when Arlington Canyon’s stream system was actively transporting and depositing material.

The individual had died near the stream — perhaps at the marshy area that Orr described as a cienaga — and had been incorporated into the accumulating sediment.

Nothing about the physical context argued for reworking.

The bones were in primary depositional context, in a stratigraphic unit whose age was independently confirmed by multiple dating methods.
