Lake Pupuke

Lake Pupuke is a heart-shaped freshwater lake occupying a volcanic explosion crater (or maar) between the suburbs of Takapuna and Milford on the North Shore of Auckland, New Zealand. The heart shape is a result of its formation by the linking of two circular craters - a larger one forming most of the lake and a smaller one forming the arm in the northeast. Separated from the sea by less than 200 m at one point, it has a circumference of about 4.5 km and reaches 57 m in depth. It is popular for recreational activities and the lakefront property around it. Other similar craters in the Auckland Volcanic Field were either buried by later eruptions, or breached by erosion as rainwater collected and overflowed the edge of the crater. Lake...
