Because andesite is the main type of lava erupted from Mount Price, lava flows are a low to moderate hazard. Andesite lava is intermediate in silica content, indicating that it has a higher viscosity than basaltic lava, but less viscous than dacite and rhyolite lava. As a result, andesite lava flows typically move slower than basaltic lava flows and are less likely to travel far from their source. Dacite and rhyolite lavas are normally too viscous to flow far from a volcanic vent, resulting in the formation of lava domes. An exception is the long Ring Creek dacite lava flow from Opal Cone on the southeastern flank of Mount Garibaldi, a length that is normally attained by basaltic lava flows.
