sand - set of two 2-ounce jars of brown beach sand derived from the Franciscan Complex
The source of this sand is the rocks of the Late Mesozoic Franciscan Complex. This is a chaotic assemblage of rocks that were scraped off the Farallon Plate as it subducted under the North American Plate. The Franciscan has widespread distribution in the Coast Ranges of California.
The entire short 200 meter long Rockaway Beach, just south of Pacifica, California, is composed of this chocolate brown sand. Many beaches where the sand source is the metamorphic rocks of the Franciscan assemblage have relatively dark sand, often grayish.
Set of two 2-ounce jars. You can mix and match, substituting any of the other sands we have in stock for one of these jars.
