Pangboche is a youngimpact crater onMars, in theTharsis quadrangle near the summit ofOlympus Mons.[1] It was named aftera village in Nepal.[2] It measures 10 kilometer in diameter, and is at 17.47° N and 133.4° W.[2]

The average depth of the crater is 954 m, and the height of the crater rim varies between 80 and 240 meters.[1] Pangboche formed in young lava flows on the flank of Olympus Mons.[1] The morphology of Pangboche is very similar to that of lunar craters, likely due to the lack of volatiles in both the atmosphere and the target.[3] It lacks several features often attributed to the presence of volatiles in the target rocks, including layered ejecta and lobate flows. It is a complex crater featuring a flat floor and several terraces.[1] Pangboche is estimated to be less than 240 million years old.[1][4]
