An incandescent lava fountain rises from MacKenney crater, which at this point, early in the 1965-1989 eruption, lay well below the summit of the cone. The date of the photo is not certain, but may have been around 1967. This view looks west from the summit of MacKenney cone with the slopes of Agua volcano in the right distance.
