These shoalds are the bottome of mar Bermejo, or the Bay of California.
The expedition of 1884 brought the Argentine army as far as the Bermejo, and broke the resistance of the Tobas.
The prisoners were carried to Panama, where they, and those others who were taken at the defeat of Bermejo, were all put to death.
In other places—south-westward of the Sierra de la Famatina, as far as the Bermejo—the outcrop is of red sandstone only.
Neither at the time of Schmidt, nor afterwards, was there at the head of the Bermejo a people called Duechkamin.
