The area are the source of several streams including Ribeira do Tarrafal which flows westward to Tarrafal de Monte Trigo.

The mountain forms part of a natural park.[2] It contains 61% of the endemic angiosperm plants of Cape Verde, of which 25% are in the red list of endangered species. The causes relate to overgrazing.[3]

Its last eruption took place over 200,000 years ago and was a Plinian eruption and shrunk the Trigo Bay around 500 meters (1,500 feet). Much of the western terrain are of lava flows of the last eruption and made the Coroa and Tarrafal Group of rock formations.[4]

The Proto-Coroa Group of rock formation formed around 400,000 years ago which is largely now covered over the two later rock formations,, it mainly consists of nephelite rocks.

During the Ice Age, its mountain elevation was around 2,100 meters tall (over 2,000 meters), when sea levels rose, 5,000 years ago, its elevation dropped below the height of 2,000 meters above sea level.

The peak has a lot of flora, of which much of it are flowers or grasses, those listed endangered includes Tornabenea insularis.
