Crystal Mountains (Africa)

Crystal Mountains (Monts de Cristal) is a group of low mountains (or hills, as all peaks are below 1,000m) inland of the Atlantic coast of Equatorial Guinea, Gabon, the Republic of the Congo, the Democratic Republic of the Congo, and Angola. It is the edge of the interior Woleu-Ntem Plateau against the coastal lowland which has a steep descent deeply cut by streams and waterfalls.
