Mortar, benchmark, cupules.
In a previous post we wrote about a United States Geological Survey benchmark medal adhered to a Chumash mortar stone, adjacent the Santa Ynez Mountains along the southern-most edge of Santa Barbara County.
Here we call attention to another example of metaphor in metal and stone, adjacent the Sierra Madre Mountains along the northern-most edge of Santa Barbara County.
The benchmark is seated amid what appears to be a series of cupules. Perhaps a cupule itself was used as a small bowl and filled with adhesive mortar and the benchmark placed on top.
A much larger, more prominent bedrock outcrop rises from the grassland near the mortar stone, suggesting the medal was intentionally set upon the Indian artifact like a flag, for reasons other than need of a solid footing in a precise location.

USGS benchmark dated 1934, Cuyama Valley.
