The low ridge in the center of the photo consists of early Holocene lava flows that originated from Clinker Peak on Mount Price to the south (out of view to the left). The lava flows ponded against the retreating continental glacier that filled the Cheakamus River valley to a depth of 1 km and formed a barrier that created Garibaldi Lake.
