Twilight colors shade the snow-capped slopes of Hekla, one of Iceland's most active volcanoes. Hekla's elongated profile is apparent in this view from the north of the 5.5-km-long summit ridge. The Heklugjá fissure which runs along the length of the ridge has been the site of numerous historical eruptions and is often active along its full length.
