Artynia Catena, as seen by HiRISE. Scale bar is 1,000 m (3,300 ft) long.

Artynia Catena is a catena in the Arcadia quadrangle of Mars, located around northwest of Alba Mons[1] at 47°58′N 119°40′W / 47.97°N 119.67°W / 47.97; -119.67. It is 263 km (163 mi) long[2] and was named after a classical albedo feature at 54°N 137°W / 54°N 137°W / 54; -137[3] The term "Catena" refers to a chain of craters.[4]

It is believed to be formed from the Martian surface collapsing into the underground cavities, such as ancient, emptied lava tubes.[1]
