Much of Calero Park is dominated by serpentinite terrane, and therefore is host to many unique fauna and flora adapted to the high magnesium soils. Manzanita trees with their red bark and silver-green leaves dominate serpentinite areas. Mt. Umunhum and the Sierra Azul Ridge are in the distance (west).
