Peaks of the Central Group. 
Presently the sun appeared again below these clouds and 
lit up the western sky, the valley, and the vast forest of 
the Congo, which merged in the intense red of the far-off 
horizon. 
On the following morning, Laurent Petigax, Brocherel, and 
three native porters went back to fetch the loads which had 
been left on the preceding day on the pass when they came 
up from Bujongolo. The others set out on the march carrying 
the rest. They skirted the two little lakes at the foot of the 
slopes of Kiyanja, cutting their way step by step through 
the dense tangle of senecio and helichrysum. Between 
the thickets of sempervivum were found specimens of an 
exceedingly beautiful large flowering hypericum, together 
with ranunculus, several plants of the cruciferous family, 
alchemilla, balsam, robbia, etc. The valley was narrow and 
grim, shut in between steep rocks, dryer than the Mobuku, 
and showing many and clear traces of glacier action at a not 
very remote period. The whole bottom was full of moraine 
rubbish, mingled with detritus, fallen from Kiyanja. Both 
lakes are of glacial formation. Under the lower lake lies 
a frontal moraine forming a dam, with a spur of rounded 
rock. The two lakes are divided by a rocky transversal 
ridge covered with detritus. To the north of the upper lake 
lies another moraine forming a steep bank, above which a 
high plain slopes upward. Here the valley widens out about 
two-thirds of a mile. At the foot of Kiyanja is a long 
neve, formed by avalanches falling over the side. 
The valley is dominated by the southern peaks of the 
central group, from which flow down two glaciers, forming 
two sources of the torrent; the third springs from a glacier 
of Kiyanja.
