The slowly advancing blocky terminous of the westernmost of three El Cordobán drainage lava flows overrides light-colored block-and-ash flow deposits formed earlier during collapse of the moving flow front. This photo was taken on February 7, 1999, about two and half months after lava effusion began in November 1998. The flow front is about 30 m high.
