Two bold silhouettes stand impossibly close to cascading fountains of molten lava as Iceland's Mount Hekla erupts in 1970 — the sky above them a surreal gradient of crimson, rose, and violet that looks almost painted. The photographers, tripods planted on the black lava field, capture the event that geologists had waited 23 years for: Hekla's first eruption since 1947, which began on May 5, 1970 and lasted two months. Published by Sólarfilma of Reykjavík, this dramatic chrome card (No. 123) is a rare visual artifact of one of Iceland's most-watched volcanic events of the 20th century — the kind of image that defined adventure photography before the drone era made proximity unnecessary.
