The area NW of the town of Estelí (bottom-center) and east of the prominent fault-bound valley at the left contains sparsely vegetated lava flows of the Estelí volcanic field. The flows were mostly erupted from fissure vents located in valleys in the northern interior highlands of Nicaragua between the town of Estelí and the border with Honduras.
