Read the passage.

from mountaineering in the sierra nevada

Shasta, as a whole, is the single cone of an immense, extinct volcano. . . .

A broad, volcanic plain, interrupted here and there by inconsiderable chains, occupies the country east of Scott’s Mountain. From this general plain, whose altitude is from twenty-five hundred to thirty-five hundred feet, rises Mount Shasta. About its base cluster hillocks of a hundred little volcanoes, but they are utterly inconspicuous under the shadow of the great peak. The volcanic plain-land is partly overgrown by forest, and in part covers itself with fields of grass or sage. Riding over it in almost any part the one great point in the landscape is the cone of Shasta; its crest of solid white, its vast altitude, the pale-gray or rosy tints of its lavas, and the dark girdle of forest which swells up over cañon-carved foothills give it a grandeur equaled by hardly any American mountain.
