A small puff of ash emerges from the active cone inside Veniaminof caldera on August 18, 2013. A beautiful fan of lava flows active earlier in the summer descends the south flank of the cone onto glacial ice producing white steam clouds and depressions where melting has occurred. The surrounding glacier is darkened by recent ash fall.
