Chasma. Of the five major landslides, all appear to be long-runout landslides, with the ratios between the landslide runout length (L) and drop height (H) between 3.2 and 6.8; terrestrial landslide typically have L/H ratios of ~2. The runout length of the five landslides varies between 15.7 to 24.6 km, with depositional thickness at the landslide toes in the hundreds of meters. The landslides provide insight into the properties of Charon's surface material; the

Serenity Chasma, all bound by the largest cliffs of the chasm. In addition to the five most prominent landslides, numerous minor landslides too small for detailed observation have also been observed, primarily within impact craters and a small ridge inside Serenity

Serenity Chasma likely formed as Charon's subsurface ocean froze, leading to the expansion of Charon's interior and the creation of extensional tectonics. The episode of extension may have occurred between 1.7 to 2.5 billion years ago. This expansion pushed the
