The two main streams join together in the middle course of the river and the Saltoro flows for a short distance before draining into the Hughe River.

The entire valley of the Saltoro River has been carved by the action of glaciers. Deposits of moraines brought down by ancient glaciers are found all along the river right from its origin to the mouth. Small tributary snow-fed streams empty themselves into the main river, usually from hanging valleys at different places.

The discharge of this river increases in late summer when the snow on the high mountains melts at a very fast rate. The entire catchment area is devoid of a vegetative cover. Human habitation is virtually absent and the tract is bleak and desolate.
