vertical, composed of columnar basalt, and it would seem as 
if the glacier during the times of its greater extension has had 
to squeeze through this narrow strait, unable to effect any 
considerable lateral erosion in this resistant material. Closer 
study, however, reveals the fact that the buttress on the west 
side of the gorge has formerly been overridden by the ice. 
The glacier, therefore, when at its greatest height, did not 
content itself with the avenue afforded by the narrow passage, 
but overrode the obstruction of hard lava to the west, thus 
securing an outlet one-quarter to one-half a mile in width. 
Immediately below the constriction, curiously, begins the 
broad, flat floored valley of the Kautz Fork, a valley that 
seems disproportionately wide for the narrow gorge that emp- 
ties into it. It is to be remembered, however, that it received 
ice from other quarters, notably from the region above Pyra- 
mid Peak. There is even reason for believing that the Wil- 
son Glacier, when at its greatest height, overflowed eastward 
through the low pass back of Pyramid Peak and sent part of 
its volume into the Kautz valley. That that valley was once 
completely filled with ice is amply attested by the powerful 
moraines that run the entire length of the great ridge above 
the so-called “Ramparts.” 
The view into the gorge of the Kautz Glacier from the 
heights to the east is a singularly fascinating one that would 
well repay the building of a tourist trail up the ridge. The 
entire extent of Van Trump Park with its alpine ridges, gorges, 
lakes and waterfalls would thus also be opened up. 
Pyramid Glacier. From the summit of Pyramid Peak one 
overlooks a great triangular interglacier situated on a sloping 
platform between the deeply sunk Kautz Glacier on the east 
and the Wilson Glacier on the west. It bears no name, but 
certainly deserves one. Merely in order to give it a handle 
for ready reference, but without insistence upon the acceptance 
of his suggestion, the writer will speak of it here as the Pyra- 
mid Glacier. In the meanwhile he hopes the Mountaineers of 
Seattle may settle upon an appropriate appellation. 
The Pyramid Glacier heads against the great cleaver that 
descends from Peak Success. To the east it is separated from 
the Kautz by a straight, mile-long ridge covered with moraine. 
It has a length of a mile and a quarter and its greatest width 
is nearly a mile. Formerly part of its névé shed into the gorge
