Westdahl Peak, in upper left corner of image (Faris Peak in distance), was the starting point of the fissure (now appearing as sinuous ice crevasse) that extends to the cinder cone (middle right), produced in the 1991 eruption. Lava flows were fed from drainage of the fissure and from the newly formed cinder cone.
