The southern section of the Rift Valley includes Lake Malawi, the third-deepest freshwater body in the world, reaching in depth and separating the Nyassa plateau of Northern Mozambique from Malawi; it ends in the Zambezi valley. Great Rift Valley The Great Rift Valley is a continuous geographic trench, approximately in length, that runs from Lebanon's Beqaa Valley in Asia to Mozambique in Southeastern Africa. The name continues in some usages, although it is today considered geologically imprecise as it combines features that are today regarded as separate, although related, rift and fault systems.

Volcanic history of the Northern Cordilleran Volcanic Province began to form 7.5 million years ago, volcanism rates in the Northern Cordilleran Volcanic Province increased again. Early volcanic activity of the Mount Edziza volcanic complex seven million years ago constructed Armadillo Peak, the oldest and most central of the four central volcanoes comprising the complex. Its summit is capped by thick fine-grained silica-rich trachyte lava flows that ponded inside the caldera to produce a lava lake six million years ago during its final stage of activity. A massive stratovolcano was also formed on top of the Level Mountain shield volcano 7.1 to 5.3 million years ago during this increased
