The El Norte lava flows, which cover much of the northern flank of Ceboruco, were erupted along buried ring fractures within nested calderas. The flows split into two lobes, a broad northern lobe that reached the base of the volcano and a narrower NW lobe (lower right). The southern wall of the inner caldera forms the irregular ridge behind the flows (below the distant haze), with the summit cone and lava flows visible at top right.
