hierarchical_section_title: Cameroon line
context_page_description: The Cameroon line is a 1,600 km chain of volcanoes.
  It includes islands in the Gulf of Guinea and mountains that extend along the border region of eastern Nigeria and the Ambazonian region of Cameroon, from Mount Cameroon on the Gulf of Guinea north and east towards Lake Chad.
  The islands, which span the equator, have tropical climates and are home to many unique plant and bird species.
  The mainland mountain regions are much cooler than the surrounding lowlands, and also contain unique and ecologically important environments.
  The Cameroon volcanic line is geologically unusual in extending through both the ocean and the continental crust. Various hypotheses have been advanced by different geologists to explain the line.
