es, the tallest of which is Mount Makiling at in elevation. Many of the maars are aligned along a NE-SW trend. Three generations of maars are present, with the oldest being sediment-filled, like the ones found in Calauan. The youngest maars contain deep lakes with many concentrated in the city of San Pablo. The youngest maar, wide Sampaloc Lake was formed about 500–700 years ago according to local legend, the last major activity in the volcanic field. Volcanism is still evident through the presence of geothermal areas like mud and hot springs.. The areas south of Mt. Makiling is the site of one of the earliest geothermal plants in the country.
