Yosemite Waterfall Turns to Lava

Unbeknownst to most Americans, the Phillipines has more active volcanoes than almost anywhere else in the world between 18 to 25, depending on who's counting. This image is of Taal, noteworthy for Volcano Island, which is the active part and counted as separate from the much larger Taal caldera. Surrounded by a lake that now fills the ancient caldera, Volcano Island is described as the smallest active volcano in the world. (George Tapan; Courtesy of JustLuxe.com)
