November 2012 Viewer's Choice The photo above shows the Alcantara River Gorge, located between Messina and Catania in Sicily. This scenic gorge was created by an eruption of Mt. Moio, a minor scoria cone of Etna, probably around 4,500 years ago. While the lava was still hot a huge crack opened creating the original gorge. Later water flowed in and began eroding the rock. Over time, the Alcantara cut a channel through the easily erodible, angled basalt columns. Photo taken on October 28, 2012.
