The discovery of Pinnacle pass left no question as to the route to be traversed in order to reach the mountains to the westward. We returned to Camp 12, and the following day, with Crumback and Lindsley to assist us, advanced our camp across Pinnacle pass and far down the western snow-slope.
The day we crossed the pass was bright and clear in the morning, but clouds gathered around all the higher peaks about midday, vanishing again at nightfall. As it was desirable to occupy, for topographic and other purposes, a station on the top of the cliffs overlooking Pinnacle pass, we made an effort to reach the crest of the ridge by climbing up the steep scarp just at the divide, where the cliffs are lowest. While Crumback returned to Camp 12 for an additional load and Lindsley went ahead to discover a new camping place, Kerr and myself, taking the necessary instruments, began the ascent; but we found it exceedingly difficult. The outcrops of shale in the lower portion of the cliff furnished but poor foothold, and crumbled and broke away at every step. Once my companion, losing his support, slid slowly down the slope in spite of vigorous efforts to hold on, and a rapid descent in the yawning chasm below seemed inevitable, when, coming to a slightly rougher surface, he was able to control his movements and to regain what had been lost. Climbing on, we came to the base of a vertical wall of shale several hundred feet high, and made a detour to the left where a cascade plunged down a narrow channel. We ascended the bed of the stream, which was sometimes so steep that the spray dashed over us, and reached the base of an overhanging cliff of conglomerate composed of well-worn pebbles. Above this rose a cliff of snow fifty feet or more in height, which threatened to crash down in avalanches at any moment. One small avalanche did occur during the ascent, and scattered its spray in our faces. Had a heavy avalanche formed, our position would have been exceedingly dangerous; but by taking advantage of every overhanging ledge, and watching for the least sign of movement in the snow above, we reached without accident a sheltered perch underneath an overhanging cliff near the base of the snow. We then discovered that clouds were forming on all the high mountains, and shreds of vapor blown over the crest of the cliff above told us that further efforts would be useless. Seeking a perch protected from avalanches by an overhanging cliff, we had a splendid view far out over the sloping snow-plain toward the west and of the mountains bordering Pinnacle pass on the south. My notes written in this commanding station read as follows:
"Looking down from my perch I can plainly distinguish the undulations and crevasses in the broad snow-fields stretching westward from Pinnacle pass. Each inequality in the rock beneath the glacier is reproduced in flowing and subdued outlines in the white surface above. The positions of bosses and cliffs in the rock beneath are indicated by rounded domes and steep descents in the snow surface. About the lower sides of these inequalities there are in some cases concentric blue lines and in others radiating fissures, marking where the snow has broken in making the descent. The side light shining from the eastward down the long westerly slope reveals by its delicate shading the presence of broad, terrace-like, transverse steps into which the stream is divided. Were the snow removed and the rock beneath exposed, we should find broad terraces separated by scarps sweeping across the bed of the glacier from side to side. Similar terraces occur in glaciated cañons in the Rocky Mountains and the Sierra Nevada, but their origin has never been explained. The glacier is here at work sculpturing similar forms; but still it is impossible to understand how the process is initiated.
"Right in front of us, and only a mile or two away, rise the cliffs, spires, and pinnacles of the Hitchcock range. Every ravine and amphitheatre in the great mountain mass is deeply filled with snow, and the sharp angular crests look as if they had been thrust up through the general covering of white. The northern end of the range is clearly defined by the east-and-west fault to which Pinnacle pass owes its origin. The trend of the mighty cliffs on the southern face, on which we have found a perch, is at right angles to the longer axis of the Hitchcock range, and marks its northern terminus both topographically and geologically.
"There is not even a suggestion of vegetation in sight. The eye fails to detect a single dash of green or the glow of a single Alpine flower anywhere on the rugged slopes. A small avalanche from the snow-cliffs above, cascading over the cliff which shelters me and only a few yards away, tells why the precipices are so bare and desolate: they have been swept clean by avalanches.
"Far down the western snow-slope I can distinguish crevasses and dirt bands in the Seward glacier, which flows southward past the range on which we sit. The marginal crevasses along the border of the glacier can clearly be distinguished. As usual, they trend up-stream and, meeting medial crevasses, break the surface of the glacier into thousands of pinnacles and tables. Along the center of the stream there are V-shaped dirt bands, separated by crevasses, which point down-stream and give the appearance of a rapid flow to the central portion of the glacier. From this distance its center has the appearance of 'watered' ribbon.
"A little toward the south of where the medial crevasses are most numerous, and at a locality where two opposite mountain spurs force the ice-stream through the comparatively narrow gorge, there is evidently an ice-fall, as the whole glacier from side to side disappears from view. The appearance of Niagara when seen from the banks of the river above the Horseshoe falls is suggested. Beyond this silent cataract, the eye ranges far out over the broad, level surface of the Malaspina glacier, and traces the dark morainal ribbons streaming away for miles from the mountain spurs among which they originate. From the extreme southern cape of the Samovar hills there is a highly compound moraine-belt stretching away toward the south, and then dividing and curving both east and west. The central band of débris must be a mile broad. Along its eastern margin I can count five lesser bands separated by narrow intervals of ice, and on the farther side similar secondary bands are suggested, but the height of the central range almost completely conceals them from view. In the distant tattered ends, however, their various divisions can be clearly traced. Great swirls in the ice are there indicated by concentric curves of débris on its surface.
"Still farther westward there are hills rising to the height of impressive mountains, in which northward dipping rocks, apparently of sandstone and shale, similar to those forming the Hitchcock range, are plainly distinguishable. All the northern slopes of these hills are deeply buried beneath a universal covering of snow evidently hundreds of feet thick, which is molded upon them so as to reveal every swelling dome and ravine in their rugged sides. Farther westward still, beyond a dark headland apparently washed by the sea, there are other broad ice-fields of the same general character as the Malaspina glacier, which stretch away for miles and miles and blend in the dim distance with the haze of the horizon.
"Just west of the Seward glacier, and in part forming its western shore, there are dark, rocky crests projecting through the universal ice mantle, suggesting the lost mountains of Utah and Nevada which have become deeply buried by the dusts of the desert. The character of the sharp crests beyond the Seward glacier indicate that they are the upturned edges of fault-blocks similar to the one on which we are seated. Interesting geological records are there waiting an interpreter. The vastness of the mountains and the snow-fields to be seen at a single glance from this point of view can scarcely be realized. There are no familiar objects in sight with which to make eye-measurements; the picture is on so grand a scale that it defies imagination's grasp."
Searching the snow-sheet below with a field-glass, I discover a minute spot on the white surface. Its movement, slow but unmistakable, assures me that it is Lindsley returning from the site chosen for our camp to-night. Although apparently near at hand, he forms but an inconspicuous speck on the vast snow-field.
