    Importance

    The summit of Añisclo draws large numbers of groups of expert climbers every summer. The plentiful foraminiferans that are large in size and the many crab nests, built using orbitoid shells, make this a very interesting site.

    Location

    At UTM coordinates 31T 257761 4728615. The spot is just below the summit, but the entire peak is an excellent outcrop with abundant fossils.
