Garibaldi Lake Volcanic Field
Mount Garibaldi is associated with a group of small volcanoes that form the Garibaldi Lake volcanic field. An unusual volcanic structure called The Table is located between Garibaldi Lake and Mount Garibaldi. This several-hundred-foot-high flat-topped volcano is made of layers of andesitic dacite that are arranged like a stack of more or less equal sized pancakes. The Table was formed in the early Holocene at a time when the Cordilleran ice sheet covered the region. As the volcano's lava rose it melted the part of the ice sheet above The Table's vent, creating space for the lava to move into. Repeated eruptions constructed the steep-walled stack of lava seen today.
Black Tusk is a large spire of extensively eroded dark volcanic rock that is shaped like a Walrus tusk. It is considered to be the remnant of an extinct andesitic stratovolcano which formed between about 1.3 and 1.1 million years ago.
Mount Price, west of Garibaldi Lake, 5 km south of Black Tusk, was formed in three stages of activity, dating back 1.1 million years, the latest of which produced two large lava flows from Clinker Peak during the early Holocene that ponded against the retreating continental ice sheet and formed The Barrier, containing Garibaldi Lake.
Cinder Cone stands 150 m (492 ft) above a gap between two arms of Helmet Glacier on Garibaldi's flanks. During summer its crater is filled with a snow melt lake.

“Yet, hermit and stoic as he was, he was really fond of sympathy, and threw himself heartily and childlike into the company of young people whom he loved, and whom he delighted to entertain, as he only could, with the varied and endless anecdotes of his experiences by field and river: and he was always ready to lead a huckleberry-party or a search for chestnuts and grapes.”
—Ralph Waldo Emerson (18031882)
“Each of us, even the lowliest and most insignificant among us, was uprooted from his innermost existence by the almost constant volcanic upheavals visited upon our European soil and, as one of countless human beings, I cant claim any special place for myself except that, as an Austrian, a Jew, writer, humanist and pacifist, I have always been precisely in those places where the effects of the thrusts were most violent.”
—Stefan Zweig (18811942)
“They who know of no purer sources of truth, who have traced up its stream no higher, stand, and wisely stand, by the Bible and the Constitution, and drink at it there with reverence and humility; but they who behold where it comes trickling into this lake or that pool, gird up their loins once more, and continue their pilgrimage toward its fountain-head.”
—Henry David Thoreau (18171862)
