Geography
The creek in Diano San Pietro

The creek is formed close to the village of Evigno (comune of Diano Arentino) from the union of several streams descending the south-eastern slopes of monte Torre (990 m)[2]. Going SSW, a direction the creek wil keep till to its mouth, it reaches Diano San Pietro where it gets from the left rio Beste, its main tributary. San Pietro watercourse marks for a long stretch the border between the comuni of Diano Castello (West side) and Diano San Pietro. Not faraway from its mouth, which is located in comune of Diano Marina, the San Pietro is crossed by Genoa–Ventimiglia railway, Autostrada dei Fiori and State highway nr.1 (Via Aurelia).

The valley of San Pietro is also called Valle Dianese and borders to the West with Impero valley, to the North for a short stretch with Merula valley and to the East with Steria valley.

San Pietro basin (18 km2) is totally included in the Province of Imperia.[4]

Fishing
San Pietro mouth

The San Pietro is not considered very suitable for fishing; between Roncagli and Diano San Pietro among its scarce fish fauna cyprinis tend to prevail.[1]

gollark: But having access to several orders of magnitude of computing power than exists on Earth, and quantum computers (which can break the hard problems involved in all widely used asymmetric stuff) would.
gollark: Like how in theory on arbitrarily big numbers the fastest way to do multiplication is with some insane thing involving lots of Fourier transforms, but on averagely sized numbers it isn't very helpful.
gollark: It's entirely possible that the P = NP thing could be entirely irrelevant to breaking encryption, actually, as it might not provide a faster/more computationally efficient algorithm for key sizes which are in use.
gollark: Well, that would be inconvenient.
gollark: Increasing the key sizes a lot isn't very helpful if it doesn't increase the difficulty of breaking it by a similarly large factor.
