BeschreibungThe earliest known activity at the Leonard Range was 1.1 million years ago. A series of lava domes were built in the area around Lake Leonard from about 290,000 years ago. The latest epoch of activity occurred during the past 20,000 years and produced the Paloc pyroclastic deposits during an eruption between 6,000-1,800 years ago, which also formed the caldera.
The Leonard Range (or North Davao) area is the site of a geothermal exploration program.
Manat thermal area is located north of Lake Leonard, solfataras occur its SW rim, and active solfataras, fumaroles, and hot springs are found in the Amacan-Gopod thermal area south of the lake.
Lake Leonard is located inside the caldera and contains freshwater with fish species including Anguila pacifica, Clarias batrachus, Glossogobius giurus, Ophicephalus striatus and Tilapia mossambica. It is also home to the the endangered Philippine crocodile Crocodylus mindorensis which is found at the lake during the breeding season in July-September.
