The solitary tree on Lake Canterno is a testament to the lake's karst and mysterious nature. Its fame stems from the fact that, due to the lake's unstable water level, this small tree is periodically submerged and then resurfaces during times of drought, resulting in much-photographed imagery and becoming a symbol of the "ghost" lake.
