The 1670 lava flow covering much of this photo originated from Nindirí crater on the horizon. A lava lake in the crater eventually overflowed the rim, producing a lava flow that traveled from Nindirí crater for 5 km down the northern flank of Masaya's post-caldera cone. Some accounts confused the 1670 flow from Nindirí with the 1772 flow from Old Masaya crater.
