Created over 160 million years ago under extreme fire and pressure, the “igneous” and “metaphoric” rocks of Hot Springs Cove ( originally know as Refuge Cove) reveal this as a place of dynamic geological activity. This part of Vancouver Island rests on a unstable portion of the earths crust, known as a “fault”. This major fault, extending offshore from Mate Island, north along the west side of Hot Springs Cove to Hesquiaht Lake is associated with intense heat and pressure generated from deep within the earth.
Maquinna Park’s main feature, Sharp Point Hot Springs, ranks as a major thermal spring in Canada, with a high water discharge of about 5 to 8 litres per second. The hot spring is a result of surface water flowing through a “fault” to a depth of about 5 kilometres. The water is geothermally heated to a temperature of at least 109 degrees C before hydrostatic pressure forces the water back to the surface and discharges through fractured rock at a temperature of about 50 degrees C.
