Dramatic Miranda

Miranda displays a dramatically varied surface. Easy to see in this 660m (2160 ft) wide image are numerous ridges and valleys -- a topography that was probably produced by compressional tectonics. Cutting across Miranda's ridges and valleys are many faults. The largest fault scarp is seen below and right of center; it shows grooves probably made by the fault blocks as they rubbed against each other (leaving what are known as slickensides). Movement of the down-dropped block is shown by the offset of the ridges. The fault may be 5 km (3 mi) high, or higher than the walls of the Grand Canyon on Earth.
