Leonard Range (also known as Leonard Kniazeff) volcano is an andesitic-dacitic volcanic complex with a 4x5 km caldera. It is located east of Davao Gulf in SE Mindanao, east of the major N-S-trending Philippine Fault and belongs to the East Mindanao Arc.
The last activity of Leonard Range probably occurred about 1800 years ago, indicated by radiocarbon dating of charred wood found in a pyroclastic flow deposit on the edge of the caldera.
Several thermal areas and solfataras occur at Leonard Range.

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.

Another hour’s drive from Mainit is the majestic Lake Leonard. The caldera lake formed from the crater of the active volcano Leonard Kniaseff stretches 203 km in diameter against a mountain range coated in lush green.
