Mount Shasta, a colossal volcanic cone, rises to a height of
14,440 feet at the northern extremity, and forms a noble landmark for
all the surrounding region within a radius of a hundred miles. Residual
masses of volcanic rocks occur throughout most of the granitic southern
portion also, and a considerable number of old volcanoes on the flanks,
especially along the eastern base of the range near Mono Lake and
southward. But it is only to the northward that the entire range, from
base to summit, is covered with lava.
From the summit of Mount Whitney only granite is seen. Innumerable peaks
and spires but little lower than its own storm-beaten crags rise in
groups like forest-trees, in full view, segregated by canons of
tremendous depth and ruggedness. On Shasta nearly every feature in the
vast view speaks of the old volcanic fires. Far to the northward, in
Oregon, the icy volcanoes of Mount Pitt and the Three Sisters rise above
the dark evergreen woods. Southward innumerable smaller craters and
cones are distributed along the axis of the range and on each flank. Of
these, Lassen's Butte is the highest, being nearly 11,000 feet above
sea-level.
