Between Coe and Ladd glaciers is a high rocky ridge known as Barrett Spur, from which, at nearly 8,000 feet, one may obtain glorious views of the peak above, the two glaciers sweeping down its steep face and the sea of ranges stretching westward. (See illustrations, pp. [69] and [75].) Barrett Spur may have been part of the original surface of the mountain, but is more likely the remnant of a secondary cone, ice and weathering having destroyed its conical shape. From its top, the climber looks over into the broad-bottomed canyon of Sandy River, fed by the large and small Sandy glaciers of the west slope. (See pp. [71] and [76].) This canyon and that of the Zigzag River, south of it, from Zigzag glacier, are "plainly glacier-sculptured," as Sylvester declares. The same is true of the canyon lying below the White River glacier, on the southeast slope. In journeying to Government Camp, one may see abundant evidence of the glacial origin of the Sandy and Zigzag canyons. The White River Canyon has been thoroughly explored and described by Prof. Reid.

All three of these wide U-shaped canyons were once occupied by great glaciers, which left their record in the scorings upon the sides of the gorges; in the mesas of finely ground moraine which they spread over the bottoms and through which the modern rivers have cut deep ravines; in trees broken and buried by the glaciers in this drift; in the fossil ice lying beneath it, and in huge angular boulders left standing on the valley floors, several miles from the mountain.

Sandy glacier extends three hundred feet farther down the slope than do the north-side glaciers, but the Zigzag and White River glaciers, flowing out of the crater, end a thousand feet higher. This is due not only to the smaller reservoirs which feed them and to their southern exposure, but also doubtless to the easier grade, which holds the ice longer on the slope. On the east side of the peak is a broad ice-stream, the Newton Clark glacier, which also ends at a high altitude, dropping its ice over a cliff into deep ravines at the head of East Fork of Hood River. This glacier, well seen from Cooper Spur, completes the circuit of the mountain. (See pp. [83] and [84].)

Sylvester suggests that Mount Hood may not be extinct but sleeping. For this, however, there is little more evidence that may be discovered on other Northwestern peaks. About Crater Rock, steam jets are found, gas escapes, and the rocks are warm in many places. "Fumaroles" exist, where the residuary heat causes openings in the snow bed. Sylvester reports dense smoke and steam issuing from Crater Rock by day and a brilliant illumination there at night, in August, 1907. But volcanoes sometimes contradict prophecy, and no further intimations of trouble having since been offered, this display may be deemed the last gasp of a dying monster rather than an awakening toward new life.
