The reserve is mainly the crater of an extinguished volcano, that now has become a plain surrounded by the crater walls covered with forest. In the plain inside the crater agricultural activities have been carried on since the time of the Incas, which barely alter the ecosystem. However, mining endangered the unique qualities of the zone, since a habitable crater is not very common, until it was protected.
