Very different in character and in appearance from the region we were leaving behind was the slope which faced our encampment, robed in perpetual snow. You have pursued the ramifications of the lava system to the side of their parent stems; and in place of blind troughs and prospectless ledges a noble singleness of feature breaks upon the extricated view. You command the whole summit structure of Ararat on the short, or gable side; and the shape which rises from the open ground about you is that of a massive cone. The regular seams which mount to the summit stretch continuous to the crown of snow, and are inclined at an angle which diverges very little from an average of 30°. The gradients from which these higher seams gather--the slopes about our camp--cannot exceed half that inclination, or an angle of 15°. Such is the outline, so harmonious and simple, which a first glance reveals.... A more intimate study of the summit region, as it expands to a closer view, disclosed characteristics which were not exactly similar to those with which we had already become familiar in the neighbourhood of Sardar Bulakh. It was there the north-eastern hemisphere of the mountain--if the term may be applied to the oval figure which the summit region presents--displayed to the prospect upon the segment between east and south-east. Our present position lay more to the southward, between the two hemispheres; we were placed near the axis of the figure, and the roof, as viewed from our encampment, bore nearly due north-west. The gigantic causeway which at Sardar Bulakh was seen descending on our left hand from the distant snows, now rose on our right, like a rocky headland, confronting a gleaming sea of ice. But, when the eye pursues the summit circle vanishing towards the west, you miss the sister forms of lesser causeways, radiating down the mountain side. It is true that the greater proximity of our standpoint to the foot of these highest slopes curtailed the segment of the circle which we are able to command. This circumstance is not in itself sufficient to explain the change in the physiognomy of the summit region, as we see it on this side. In place of those bold, black ribs or ridges, spread fanwise down the incline, furrowing the snows with their sharp edges, and lined along the troughs of their contiguous bases with broad streaks of sheltered nevé, it seems as if the fabric had fallen asunder, the surface slipped away--all the flank of the mountain depressed and hollow, from our camp to the roof of the dome. The canopy of snow which encircles the summit--a broad, inviolate bank, unbroken by any rift or rock projection for a depth of some 2000 feet--breaks sharply off on the verge of this depression, and leaves the shallow cavity bare. From the base of the giant causeway just above us to the gently-pursing outline of the roof you follow the edge of the great snow-field, bordering a rough and crumbling region which offers scanty foothold to the snow, where
