Dorsa Smirnov

The Dorsa Smirnov is an approximately 220 km long group of Dorsa on the Earth's moon. It was named after the Soviet Sergei Sergeyevich Smirnov geoscientists 1976.

It is not entirely clear how far the structure extends to the north. The approximate center is indicated by the small crater Very. At the southern end of the ridge disappears almost entirely in the Mare - level before it continues in the dorsum Lister. The northern end is later than the crater Posidonius Y, where the ridges bifurcate.

Johann Hieronymus Schroeter called an extended structure extending from dorsum Nicol, Dorsum Lister, Dorsa Smirnov and an unnamed ridge that runs from Posidonius Y to the northeast and ends at Posidonius F, as " core " and "true, serpentine continuous, flat gebauetes, low mountains ". According to this Schroeterschen name appears in the structure of English literature with the unofficial designation Serpentine Ridge.
