Arkhangelsky Crater is a crater in the Argyre quadrangle of Mars, located at 41.4° S and 24.8° W, and is inside Noachis Terra east of Nereidum Montes. It is 125 km across and was named after A.D. Arkhangelsky a Russian geologist.[1] Nearby prominent craters include Hartwig to the east, Lohse and Helmholtz to the east-southeast, and the notable Galle to the north. Other are the smaller Kakori and Tarakan to the west and the tiny Flateyri further north-northwest.
Arkhangelsky is notable for having gullies on the crater rims within the top, some have patterned ground in a shape of polygons. Old glaciers are founded where the curved ridges are located inside the crater floor. Also inside as to the planet's majority of its craters are dunes.
