 Mount Price, a less significant stratovolcano just north of Mount Garibaldi, formed during three distinct periods of volcanic activity beginning at 1.2 million years ago and culminating with the eruption of Clinker Peak on its western flank 0.3 million years ago.In addition to the large, central andesite-dacite volcanoes, the southern portion of the Garibaldi Volcanic Belt includes remnants of basalt and basaltic andesite lava flows and pyroclastic rocks.These include valley -filling lava flows interbedded with till containing wood about 34,000 years old.
