539 km. are caused by heavy beds of coarse conglomerate 

 of the Laberge series, which cross the river 

 at that point. At one time, a fall probably 

 existed there, but the barrier has now been cut 

 through at several points, giving the rapids the 

 appearance intended to be conveyed by their 

 name. The massive rock buttresses and the 

 narrow tongues or rushing water between, 

 have a formidable appearance. River steamers, 

 however, go through without much difficulty 

 at most seasons, but when the water is high, 

 upstream boats have to be lined through with 

 a cable attached to the bank above. 



343 m. Rink Rapids — Rink rapids have more the 



548 km. appearance of a broad stony riffle than a rapid, 



although, especially in high water, the current
