On November 3, 2001 this spine-capped lava dome was observed on the north side of Colima's summit crater. The spine was about 40 m tall, 40 meters wide at its base, and smooth with vertical walls.  Extrusion of this new dome had begun in early October and continued with a high growth rate, reaching a maximum on October 14. The spiny extrusion probably occurred around this day and was accompanied by small explosions.  This was part of a long-term eruption that began in November 1997.
