Baghdad Rytvins ( English Baghdad Sulcus ) - potholes (relief of alternating furrows and ridges) on the surface of the moon of Saturn - Enceladus . They are one of the four “ tiger stripes ” through which the ice resting in the ocean inside the satellite erupts into the surrounding space.

Geography
The approximate coordinates of the object are [1] . Potholes are located in the southern polar region of Enceladus. To the west of it are the Cairo pothole , and to the east is the Damascus pothole .
Geology
The length of the potholes is 176 km . In the north, potholes are formed by two faults, which form the shape of the English letter "V". This fault, apparently, is one of the youngest parts of the near-polar region of the satellite. Its depth is estimated from 200 to 250 meters , width - 2 km , and the height of the surrounding walls is approximately 100 meters [2] . It is surrounded by coarse-grained water ice deposits (which looks pale green in spectrozonal images obtained by combining images in the ultraviolet, green, and near infrared ranges). Its presence indicates that the region is quite young and has not yet been covered with fine-grained ice from the E-ring. The results of spectrometry in the visible and infrared regions show that the greenish ice in the tiger bands differs in composition from the ice of other parts of the surface of Enceladus. Spectrometric detection of fresh crystalline water ice in the bands indicates the youth of these sites (under 1000 years old) or their recent re-melting [3] . In addition, simple organic compounds were found in tiger stripes that have not yet been found anywhere else on the surface [4] .
Eponym
Named in honor of Baghdad - the city featured in the collection of Arabic fairy tales One Thousand and One Nights . The official name was approved by the International Astronomical Union in 2006 [1] .
