From Dipolog City eastward along the northern coast of Mindanao approaching Butuan City extends a rolling coastal plain of varying width. In Misamis Occidental, the now dormant Mount Malindang has created a lowland averaging in width. Shallow Panquil Bay divides this province from Lanao del Norte, and is bordered by low-lying, poorly drained lowlands and extensive mangroves. In Misamis Oriental, the plain is narrower and in places whittle into rugged capes that reach the sea. East of Cagayan de Oro, a rugged peninsula extends into the Mindanao Sea.
