Steaming MacKenney cone is seen here from the NW below Cerro Chino cinder cone, whose ash-mantled slope appears at the left. Dark-colored lava flows that were erupted in 1998 descend from the summit and cascade down from the caldera moat at the left. This flow and the two dark lobes above it originated from MacKenney cone during the September 18-19, 1998 eruption. Light-colored tephra deposits between the flows mantle previous lava flows.
