Bazman volcano in Iran is featured in this image photographed by an Expedition 38 crew member aboard the ISS on January 5, 2014. Bazman volcano is located in a remote southern region within the Bazman Protected Area of Sistan and Baluchestan Provinces.
While the volcano has the classic cone shape associated with stratovolcanoes, it is also heavily dissected by channels that extend downwards from the 3,490-meter-above-sea-level summit. This radial drainage pattern - looking similar to the spokes of a bicycle wheel - is readily observed in this photograph.
Such patterns can form around high, symmetric peaks when water runoff and erosion is not constrained by the resistance of geologic materials or barriers to flow, leading to essentially even distribution of water runoff channels around the central peak. (NASA)
