A prominent notch cuts the steaming summit crater of MacKenney cone on Pacaya in this February 1999 aerial view from the north. A trail in the foreground tracks the rim of a large horseshoe-shaped caldera inside which the cone was constructed. Lava flows from the summit crater and flank vents of MacKenney cone have poured into the caldera moat and subsequently been deflected to the west and south.
