Gulugod Baboy is a Tagalog word which means “pig’s spine”. It was said that that mountain was named as such due to the outline of its peaks that resemble a pig spine itself. It has three peaks: The Gulugod Baboy (470 MASL) , Gitna (485 MASL) and Pinagbanderahan (525+ MASL).
The highest of the three peaks actually has a history the reason why it was called as Pinagbanderahan. Around 1940’s during the World War II, a Japanese aircraft crashed into it. With sheer luck, the Japanese airmen in it survived. To celebrate the chance to life, they hoisted a flag at the mountain; thus, pinagbanderahan. Pinagbanderahan is a Tagalog term which came from the borrowed word, bandera, which means flag.
