part of the wall of the enormous amphitheater under Liberty 
Cap. This amphitheater, which is second only to that of the 
Carbon Glacier, contributes a very considerable share of the 
total bulk of the Tahoma Glacier, perhaps as much as 30 per 
cent. Strangely, the union of its ice mass with that coming 
down over the cascades does not give rise to a medial moraine. 
It will require further investigation to determine the reason 
for this striking anomaly. 
Farther down the Tahoma Glacier broadens to a width of 
shghtly more than a mile, presenting an unruly, billowy sur- 
face, diversified by numerous crevassed domes and abrupt ice 
cascades. Approaching Glacier Island, the great stream con- 
tracts until at the west end of the island it measures only 
1,700 feet across. Immediately below this point the glacier 
splits upon a low wedge, sending one lobe to the south and 
another to the southwest. The south lobe joins the Wilson 
Glacier under Glacier Island and thus becomes tributary to 
the Tahoma Fork. The southwest lobe continues by itself for 
a distance of a mile, giving birth to the southernmost fork of 
the Puyallup River. The south lobe, it may be added, is ac- 
companied on both sides by splendidly developed lateral mo- 
raines; the moraine at the foot of Glacier Island especially is 
perfect and worthy of a visit. 
Measured from Columbia Crest down to the end of the 
southwest lobe (which has an elevation of about 4,800 feet), 
the Tahoma Glacier is found to be exactly five miles long. 
Measured to the foot of the Tahoma Fork lobe it is five and 
three-fourths miles lone. 
Puyallup Glacier. The same amphitheater that contributes 
so generously to the Tahoma Glacier also initiates the Puyallup 
Glacier, the next ice stream to the north. In the center of the 
amphitheater rises a bold pinnacle of black rock which parts 
the névés and from which trails the long and exceedingly 
narrow rock cleaver that separates the ‘Puyallup from the 
Tahoma Glacier. 
On issuing from the cirque the Puyallup Glacier passes 
through a chute only 1,200 feet in width. A short distance 
below part of its mass is diverted northward to the Edmunds 
Glacier; yet notwithstanding this small beginning and imme- 
diate loss the Puyallup farther down spreads out to a width 
of three-quarters of a mile and then to a full mile, and attains
