that found evidence for the large clockwise rotation of the Transverse Ranges in California. Uplift along the Santa Ynez Fault during the Quaternary period – the last 2.5 million years – has brought the Coldwater and the other formations up from their deposition environments to their present prominent locations in the Santa Ynez Range. In the area north and northeast of Santa Barbara, on the south slope of the Santa Ynez Mountains eastward to near Ojai, the compression and folding associated with tectonic movements have been sufficiently intense to overturn the rock units so that the older ones are on top. This stretch of overturned rock formations is known as the "Montecito Overturn". Paleontology Fossils of numerous mollusks, including many species of the genus Turritella can be found in the Coldwater, particularly near the top of the formation where the water at time of deposition was shallowest. Outcrops along Old San Marcos Pass Road above Goleta and near the contact with the Sespe Formation are rich locations for finding remnants of these sea-snails. Elsewhere near the top contact with the Sespe, the remnants of oyster beds can be found.
