 This sites most notable feature is the "El cráter de Pululahua" which is one of only two volcanic craters inhabited in the world (and the only one that is farmed and agricultural produce is used to sustain the population and can be sold for profit).Often, this reserve is shrouded in a thick layer of clouds or fog.The land here is extremely fertile because it is volcanic (igneous) soil and, as mentioned earlier, is used to cultivate crops.
