This drawing depicts a precisely identifiable range of hills in the Pisa mountains near Cascina. This topographical record should be regarded as a preparation for a map of a canal project which Leonardo developed for the Florentine Signoria. The intention was to create a navigable trade route from Florence to the ocean.
