The guardians of the Columbia, Mount Hood, Mount Adams and Mount St Helens . Northwest slope of Mount Adams, with Adams glacier, three miles long, the largest on the has an ice-fall of two thousand feet. The low-lying reservoir of Pinnacle glacier is on extreme right,and the head of Lava glacier on left. from the snow line. Visitors from Portland, Tacoma or Seattle, bound forthe north side, leave the railway at Castle Rock, whence a good automobileroad (forty-eight miles) leads to the south side of Spirit Lake. Petersonsmay be reached by road from Woodland (forty-five miles) or from Yacolt(thirty miles). Well-marked trails lead from either base to camping groundsat timber line. The mountain is climbed by a long, easy slope on the south,or by a much steeper path on the north. Like Mount Adams, St. Helens is largely built of lava, but the outflowshave been more recent here than upon or near the greater peak. The volcanowas in eruption several times between 1830 and 1845.

The latter, however, derivesmost of its support from slopes farther to right. Note the huge terminal moraines built by theseglaciers in their retreat. Pinnacle glacier is on extreme left. was often darkened, and ashes were carried as far as The Dalles. To thesedisturbances, probably, are due the great outflows of new lava covering thesouth and west sides of the mountain, and much of the country between it andthe North Fork of Lewis River. The molten stream flowed westward to GoatMountain and the Buttes, of which it made islands; threw a dike across awatercourse and created Lake Merrill; and turning southward, filled valleysand overwhelmed good forest with sheets of basalt.
