    A. Evolution of Cave

    One of the wonders of the natural world are caves, which are usually hidden

    among mountains and inside them are awesome cathedrals of stone and

    considered as unique, natural, and non-renewable resources with important

    scientific, economic, educational, cultural, historical, and aesthetic values.

    Caraga Region is among the places in the Philippines where limestone deposits

    are very rich with diverse natural resources and distinct characterization of flora

    and fauna. Based on the actual cave assessment conducted by the DENR

    PENRO SDN together with the personnel from the Regional Office, it revealed

    that the cave has a unique features that the municipality can be proud of.

    Just like other caves in the Philippines, Patag Cave which is situated in the

    Municipality of Burgos was originated and formed through the creation of

    limestone which gradually dissolved with the interaction of rainwater and

    groundwater thus creating a hole forming tunnel, large caverns and other

    irregular passages. Frequently, water charged with mineral seeps into the cave

    and evaporates leaving stalactite deposits that hang from the roof and

    stalagmite deposits that grew from the floor. As stalactite grows downward and

    stalagmite grows upward they may eventually join to form a column. Such

    formation is natures action that forms the caves.

    B. Geographical Location and Description

    h.2. Status of the Cave

    Since some of the local communities including local and foreign visitors are

    entering the cave, the Patag Cave is no longer pristine/virgin but still intact. As

    mentioned earlier, the cave area is a source of irrigation to farmers nearby or in

    the low land particularly in Patag area since the cave has an underground river

    system. According to the farmers, the river system of the cave can irrigate rice

    fields of about 4-5 hectares during dry season and 8-10 hectares during wet or

    rainy season. At present, seven (7) farmers in the Patag area had benefited from

    it. There were no distinct cave formations and minerals inside the cave except

    for some giant stalagmites, stalactites and columns in the main chamber. There

    were no vandalisms and signs of floor excavation, however there were some

    plastic leftovers observed in the area.
