Pico de Orizaba volcano is seen here from the south, with snow-free Sierra Negra volcano to its left. Sierra Negra is the southernmost major vent of the roughly NNE-SSW-trending Pico de Orizaba-Cofre de Perote volcanic chain. The construction of Sierra Negra was contemporaneous with the mid-Pleistocene early stages in the formation of Orizaba volcano. Sierra Negra is composed largely of lava flows and produced numerous pyroclastic flows mainly to the SW and W.
