The Dorsa Smirnov is an approximately 220 km long group of Dorsa on the Earth's moon . It was named in 1976 after the Soviet geoscientist Sergei Sergejewitsch Smirnow .
It's not entirely clear how far the structure extends north. The approximate center is indicated by the small Very crater . At the southern end, the ridge disappears almost completely into the Mare plain before continuing in the Dorsum Lister . The northern end is at the latest at the Posidonius Y crater , where the mountain ranges fork.
Johann Hieronymus Schroeter described an extensive structure consisting of Dorsum Nicol , Dorsum Lister , Dorsa Smirnov and an unnamed ridge, which runs from Posidonius Y to the northeast and ends at Posidonius F , as "vein" and "true, serpentine, flat built, low mountain range ”. According to this Schroeter name, the structure appears in the English literature with the unofficial name Serpentine Ridge .
