Hekla has a conical profile when viewed from the SW, looking directly down the axis of the elongated volcano. Axlargigur, the WSW end of the 5.5-km-long Heklugja fissure that crosses the summit, extends toward the photographer. This fissure was active along its entire length during the 1970 eruption.
