Volcanologist Richard Heard of the Montserrat Volcano Observatory observes the new lava dome in February 1997. The surface temperature of the lava dome at this time was 650-800 degrees centigrade. By this time the new dome had grown to a height above that of Chances Peak, the former summit of the volcano and the location of this photo. A steep-sided spine forms the northern side of the lava dome. Periodic spine extrusion and subsequent collapse occurred frequently during the eruption.
