Mythology 
This mountain was referred to as Mount Hantik in the Bikolano epic Ibalong. According to the epic, the mountain was named after a large species of ants known as the Hantiks (Oecophylla smaragdina). The ants are thought to have lived in the Kalupnitan Caves (now Colapnitan) on this mountain, where Handyong drove and buried alive the crafty, sweet-voiced serpents who pretended to be charming maidens. The epic also claims that Mount Hantik, along with Mount Kulasi (now Colasi Peak) and Mount Isarog, erupted 4,500 years ago. The mountain may have possibly collapsed after the eruption, creating the smaller Mount Bernacci.
