Isalo II, also known as the Makay Formation, is an informal Triassic geological unit in Madagascar.
It is described as "thick beds of mottled red or green clays associated with soft cross-bedded sandstones, light in colour and much finer-grained than the Isalo I sandstones." It is prominent in the Makay Massif.
